The 2025 Northern Vietnam floods were a series of floods that affected Vietnam, particularly Northern Vietnam and parts of the North Central Coast, between 25 September and 16 October 2025, resulting from the combined impacts of three tropical cyclones and several other weather phenomena.
Heavy rainfall began on 25 September in northern Vietnam due to the impact of Typhoon Ragasa as it made landfall in Quảng Ninh province according to the National Center for Hydro-Meteorological Forecasting (NCHMF). The rain was subsequently intensified by an intertropical convergence zone, extending southward to the North Central Coast the following day. On 28 and 29 September, Typhoon Bualoi made landfall in HàTénh province, bringing extremely heavy rain that continued over northern Vietnam and the North Central Coast until 1 October. Shortly afterward, Typhoon Matmo moved across the VietnamâÂÂChina border area, bringing widespread rainfall to northern Vietnam from 6 to 8 October before dissipating inland. The period concluded with another spell of heavy rain between 13 and 15 October, caused by a weak cold surge interacting with an easterly disturbance. Several rainfall stations recorded historic precipitation levels during these events. Prolonged heavy rain led to rapid rises in river levels across the northern and north-central regions, with many rivers reaching Alert Level 3, the highest flood warning threshold in VietnamâÂÂs flood warning system. On the Thðáng and Cầu river basins, which form part of the upper Thái Bình river system, some stations registered record-breaking flood peaks. Extensive flooding occurred in many provinces, particularly Thái Nguyên, Bắc Ninh, Lạng Sán, and Cao Bằng. In Hanoi, torrential rain on 30 September and 7 October caused widespread urban flooding. Numerous dyke and dam failures were also reported, most notably the collapse of the Bắc Khê hydropower dam in Lạng Sán province.
This flood event, combined with typhoons Ragasa, Bualoi, and Matmo, caused severe damage to both life and property. Including the effects of the storms, the total economic losses were estimated at 35.7 trillion VND (US$1.42 billion), with 85 people dead or missing. Due to the severe impacts of the disaster, the Vietnamese government called for donations and support from both domestic and international communities.
According to VietnamâÂÂs meteorological authorities, 2025 was identified as a neutral ENSO year, with forecasts predicting 8 to 11 tropical storms and depressions forming over the South China Sea between August and October, of which 4 to 5 were expected to affect the mainland, mainly in central Vietnam. Since June 2025, the country had already experienced three major storm and flood events: the first from 10 to 13 June, caused indirectly by Tropical Storm Wutip, which brought record rainfall to parts of the central region; the second in late July under the influence of Tropical Storm Wipha; and the third in late August, associated with tropical cyclones Kajiki and Nongfa.
In September 2025, before the formation of Ragasa, tropical cyclones Tapah and Mitag developed over the South China Sea but made landfall in China, without directly affecting Vietnam. On 20 September, as Mitag weakened over land in China, Vietnamese forecasters reported the development of a new system that would later become Typhoon Ragasa, expected to intensify into a super typhoon and potentially impact northern and north-central Vietnam between 24 and 26 September. Late on 22 September, Ragasa entered the South China Sea with maximum sustained winds assessed by NCHMF to be at super typhoon threshold. Nguyá» n Hoàng Hiá»Âp, VietnamâÂÂs Deputy Minister of Agriculture and Environment, described Ragasa as the strongest typhoon ever recorded by the country over the South China Sea.
On 23 September, the Vietnamese government issued an official telegram to prepare for Ragasa and warned of possible subsequent storms and flooding. According to Vietnam's meteorological authorities, Ragasa weakened below super typhoon intensity on 24 September and continued to lose intensity as it neared Móng Cái, Quảng Ninh province. Meanwhile, Bualoi developed east of the Philippines and tracked westward toward the South China Sea, with domestic forecasts indicating a potential impact on Vietnam and heavy rainfall. The government subsequently issued a series of official directives and telegrams in late September and early October in response to Bualoi, Matmo, and the ensuing floods.
On 25 September, Ragasa moved into the coastal waters of Quảng Ninh province and weakened into a tropical depression before making landfall and further dissipating into a low-pressure area. The stormâÂÂs remnant circulation, followed by the influence of an intertropical convergence zone, brought widespread heavy rainfall across the northern provinces beginning on the same day.
Three days later, on 28 September, Bualoi made landfall in HàTénh provinceâÂÂnorthern Quảng Trá» province, producing another episode of extensive heavy rainfall that persisted until 1 October. According to VietnamâÂÂs meteorological authorities, accumulated rainfall during this period generally ranged from to , while southern Sán La, southern Phú Thá»Â, Lào Cai, and Hanoi recorded totals between and . From Thanh Hóa to Huế, rainfall reached , with Thanh HóaâÂÂNghá» An and Huế experiencing , and some locations exceeding .
Several sites reported exceptionally high totals, including TàSi Láng (Lào Cai) , Km46 (Sán La) , Ngá»Âc Sán (Phú Thá»Â) , Xuân Bình (Thanh Hóa) , Cẩm Liên 2 (Thanh Hóa) , Mỹ Sán 1 (Nghá» An) , Hủa Na (Nghá» An) , Sán Há»Âng 1 (HàTénh) , ÃÂức Hóa (Quảng Trá»Â) , Bạch Mã (Huế) , and Quan Tðợng ÃÂài (Huế) . Seven rainfall stations recorded daily precipitation maxima exceeding their historical September records on 29 and 30 September.
In the early morning of 6 October, Matmo made landfall in Guangxi, China, before moving into the VietnamâÂÂChina border region. The northern and north-central provinces again experienced widespread heavy rain. Particularly in the northeastern region, as well as southern Tuyên Quang, Thái Nguyên, and Hanoi, rainfall totals ranged from to , locally exceeding ; Thái Nguyên province recorded , with some locations above . Notable totals included Quyết Thắng (Lạng Sán) , Há»Âng An (Cao Bằng) , Ghá»Ânh Gà(Tuyên Quang) , Gia Bảy (Thái Nguyên) , Hóa Thðợng (Thái Nguyên) , Thái Nguyên city , Bá» Hạ (Bắc Ninh) , Xuân Hðáng (Bắc Ninh) , Sóc Sán (Hanoi) , and Láng (Hanoi) . At the Thái Nguyên and Bắc Giang meteorological stations, record-breaking daily rainfall totals of and were observed on 7 October, surpassing not only previous October records but also the highest daily rainfall values ever measured at those sites.
From 13 to 16 October, northern Vietnam experienced yet another round of heavy rainfall, caused by the interaction of a weak cold surge with easterly winds on the southern periphery of a subtropical ridge. Significant totals were recorded at Tiên Yên (Quảng Ninh) , ÃÂông Long (Hðng Yên) , and Mỹ Lá»Âc (Hðng Yên) . In Haiphong, localized rainfall exceeded on 14 October.
All times in this section are in (ICT) unless noted otherwise.
Widespread heavy rainfall produced by the combined effects of three typhoons and an intertropical convergence zone over the northern and north-central provinces of Vietnam triggered a major flood across the river systems in these regions. Beginning on 27 September, river levels in northern Vietnam began to rise. The Tuyên Quang Reservoir opened eight bottom gates, the Thác BàReservoir opened three surface gates, and the Hòa Bình Reservoir opened two bottom gates to regulate flow. On the Red River system, the flood crest on the Lô River at HàGiang reached , exceeding Alert Level 3 on Vietnam's three-level flood warning system by and surpassing the historic 1969 flood peak by on 1 October. On the Thao River, the peak water level at Lào Cai was at 05:00 on 30 September, below Alert Level 3. At Yên Bái, the flood peak reached at 11:00 on the same day, above Alert Level 3. The Red River at the Hanoi station crested at on the morning of 2 October, corresponding to Alert Level 1. On the TÃÂch and Bùi Rivers, water levels remained at Alert Level 3 for several days until 5 October. By 13 October, floodwaters on the TÃÂch River in Hanoi had receded to slightly above Alert Level 1, while the Bùi, Nhuá»Â, and ÃÂáy Rivers had fallen below that threshold. In Ninh Bình province, on 1 October, flood levels on the ÃÂáy, Hoàng Long, ÃÂào, and Ninh Cá Rivers also surpassed Alert Level 3.
On the Thái Bình river system, during 2âÂÂ3 October, the Cầu River at ÃÂáp Cầu and the Thðáng River at Phủ Lạng Thðáng reached or approached Alert Level 3, while the Thái Bình River at Phả Lại rose to Alert Level 2. A week later, the upper reaches of the Thái Bình system recorded historic flood values. On 8 October, the Cầu River at Gia Bảy peaked at , exceeding the 2024 Yagi typhoon flood record by . The same day, the Thðáng River at Hữu Là ©ng (Lạng Sán province) crested at at 14:00, exceeding the 1986 historic flood level of by . On 9 October, new records were also set at Phủ Lạng Thðáng and Phúc Lá»Âc Phðáng: the Thðáng River reached at Phủ Lạng Thðáng, surpassing the 1986 flood, while the Cầu River rose to , above the 1971 record. Phúc Lá»Âc Phðáng peaked at , exceeding the 2024 record. At Cầu Sán, the Thðáng River reached , above the 2008 record. In the Cầu River basin near Hanoi, the first flood peak on the Cầu and CàLá» Rivers occurred on 3 October. A second peak followed on the CàLá» River at Mạnh Tân, reaching on 10 October, above the 2024 record, while the Cầu River at Lðáng Phúc peaked at ( above Alert Level 3) on 9 October. By 13 October, the Alert Level 3 warning was lifted for the Thðáng River at Phủ Lạng Thðáng, and Alert Level 2 warnings were withdrawn for the Cầu River at ÃÂáp Cầu and Phúc Lá»Âc Phðáng (Bắc Ninh), as well as for the Cầu and CàLá» Rivers at Lðáng Phúc and Mạnh Tân (Hanoi). On 14 October, only three stations were still reporting water levels above Alert Level 1. By 16 October, the Thðáng River at Phủ Lạng Thðáng had fallen below Alert Level 1, leaving only Cầu Sán still slightly above that mark.
On the Bằng Giang River at Cao Bằng, flood levels broke records twice during this event. On 1 October, the river crested at , surpassing the 1986 record of . At 23:00 on 7 October, it rose again to , above the 1986 peak.

By 3 October, floodwaters across the north-central region had receded, with many locations falling below Alert Level 1.
The heavy rainfall and flooding affected many localities across northern and north-central Vietnam, resulting in widespread inundation. In Hanoi, major downpours on 30 September and 7 October caused severe urban flooding at numerous sites. On 30 September, 116 flooded locations were recorded, and on 7 October, 122 flooded areas and nearly 30 paralyzed roads were reported. Flooding also occurred after Typhoon Bualoi in the provinces of Thanh Hóa, Nghá» An, Ninh Bình, Phú Thá»Â, Tuyên Quang, and Thái Nguyên. During the rainfall event associated with Typhoon Matmo, Thái Nguyên, Bắc Ninh, Lạng Sán, and Cao Bằng also experienced extensive inundation. In the final rainfall episode from 13 to 15 October, localized flooding was reported in Haiphong due to heavy rain.
A total of 84 dyke-related incidents occurred across northern provinces following the heavy rains brought by Matmo, while 50 incidents had been recorded earlier during Bualoi. At 13:30 on 7 October, the Bắc Khê 1 hydropower dam, located in Kim ÃÂá»Âng commune, former Tràng ÃÂá»Ânh district (now part of Tân Tiến commune), partially collapsed near its spillway. The initial fissure, initially small, gradually widened into a gap 4âÂÂ5 meters wide and 3âÂÂ4 meters deep.
The combination of typhoons Ragasa, Bualoi, and Matmo, together with other rain-inducing weather systems, caused 85 deaths and missing persons â 67 during Bualoi and 18 during Matmo. The total economic losses were estimated at 43.5 trillion VND (US$1.73 billion), including nearly 24 trillion VND (US$954 million) attributed to Bualoi and 19.5 trillion VND (US$776 million) to Matmo. The three typhoons and resulting floods caused an estimated 3.2 trillion VND (US$127.3 million) in damage to road transport infrastructure. According to statistics, more than 10,000 educational institutions were affected by the storms and flooding. The Department of Insurance Supervision and Management under the Ministry of Finance reported that, as of 10 October, insurance companies had documented 7 cases of human losses, with compensation estimated at 745 million VND, and 3,746 cases of property damage and other non-life insurance claims, totaling nearly 1.674 trillion VND in estimated losses.
Thái Nguyên province recorded the highest number of casualties, with six deaths, one missing person due to flash floods, and one death caused by a landslide. As of 14 October, during the provinceâÂÂs sixth PeopleâÂÂs Committee meeting addressing damage from Matmo and its remnants, economic losses were estimated at over 12.2 trillion VND. More than 200,000 houses were reported to be submerged, and approximately 1,010 houses were collapsed or severely damaged due to flooding and landslides.
The floods also damaged a large number of vehicles: 12,631 cars (nearly 8.7% of the provinceâÂÂs total) and 39,628 motorcycles were submerged or damaged. Many automobile repair garages were overwhelmed as flooded vehicles queued for rescue and repair, with restoration costs per car estimated between 30 million VND and 150 million VND, depending on the extent of damage. Numerous businesses, markets, and enterprises suffered heavy losses; the Thái Market (former Thái Nguyên city) ground floor was submerged to a depth of about 3 meters, destroying all goods, with many merchants reporting losses worth billions of ÃÂá»Âng. Several local companies reported damage ranging from a few billion to tens of billions of ÃÂá»Âng due to inundated warehouses and machinery.
In agriculture, flooding submerged approximately 4,400âÂÂ5,000 hectares of farmland, including around 2,800 hectares of rice and 1,000 hectares of crops completely lost, as well as 435 hectares of tea severely affected. Preliminary statistics indicated that more than 58,000 poultry were killed or swept away.
In terms of infrastructure, several dyke systems along critical sections such as the Chã, HàChâu, and Cầu River embankments around Thái Nguyên city suffered breaches, requiring emergency reinforcement over tens of kilometers to prevent overtopping. There were eight locations with landslides or deep flooding along national routes, including National Route 3 and the HanoiâÂÂThái Nguyên Expressway, where floodwaters reached depths of up to 45 cm. Rail services on the HanoiâÂÂÃÂá»Âng ÃÂÃÂng line were temporarily suspended. At one point, more than 320,000 households lost power across the province; the headquarters of the Thái Nguyên Power Company was flooded on the first floor, damaging equipment and 23 specialized vehicles, with losses estimated at 16 billion VND.

Many residential areas along the Cầu and Thðáng Rivers were submerged to depths of 0.5âÂÂ1.5 meters for nearly a week. Across the province, more than 15,000 households were evacuated or isolated by floodwaters, and 402 houses were reported damaged.
In agriculture, nearly 8,000 hectares of rice and crops and 941 hectares of fruit trees were inundated. More than 314,000 poultry and about 5,000 livestock were killed by floods, while 2,187 hectares of aquaculture ponds were destroyed.
In terms of infrastructure, 66 dyke-related incidents occurred in the province. In the early morning of 8 October, a 15-meter section of an inner dyke in Tiên Lục commune collapsed after being overtopped by floodwater, though no casualties occurred as residents had been evacuated beforehand. By the morning of 14 October, 17,254 households remained without power because flooded substations had not yet been restored. Approximately 240 schools and 60 medical stations were flooded or isolated.
For transportation, four locations along national highways crossing Bắc Ninh were submerged or affected by landslides, causing road blockages. In total, 684 sites suffered erosion or damage; 64 national and provincial roads were flooded, and 17 low crossings were damaged. Facing the threat that the 131-year-old Thðáng River railway bridge might be swept away, railway authorities stationed a six-car freight train loaded with 300 tons of ore on the bridge to stabilize and weigh it down against the current.
In Lạng Sán province, economic losses were estimated at over 1.05 trillion VND, largely due to the remnant circulation of Matmo. Prolonged heavy rainfall caused landslides and widespread flooding, severely affecting livelihoods, property, and infrastructure. According to the provincial PeopleâÂÂs Committee, about 5,100 households were affected: 10 houses collapsed, 1 was severely damaged, 6 sustained major damage, 2 were partially damaged, 2,158 houses were flooded, 2,577 were isolated, 249 experienced landslides, 55 were at risk of collapse, and 42 auxiliary structures were destroyed. Rising water levels along rivers inundated large areas in Yên Bình, Vân Nham, Hữu Là ©ng, Tuấn Sán, Cai Kinh, Thất Khê, Tràng ÃÂá»Ânh, and Quá»Âc Viá»Ât communes. Mountainous areas were severely impacted by flash floods and debris flows, causing heavy losses to agricultural production. Rainfall submerged about 3,894 hectares of rice, 1,028 hectares of crops, and 30 hectares of fruit trees, and damaged or uprooted 58 hectares of planted forest. In Yên Bình commune (former Hữu Là ©ng district), all 22 villages were inundated, isolating about 2,500 households. The total area of damaged rice, crops, and fruit trees reached 2,230 hectares, including 1,270 hectares of flooded rice. More than 5,000 pigs and over 50,000 poultry were killed or swept away.
However, during the partial collapse of the Bắc Khê 1 hydropower dam in Tân Tiến commune, there were no casualties, as local authorities evacuated residents in time. Initial damages from the incident were estimated at 50 billion VND. Thiá»Ât hại ban ÃÂầu do vụ vỡ ÃÂáºÂp gây ra ðá»Âc tÃÂnh 50 tá»· ÃÂá»Âng.
The remnants of Matmo brought heavy to very heavy rainfall to Cao Bằng province, causing severe flooding and landslides. Preliminary reports indicated seven deaths and five injuries; more than 14,000 houses were collapsed, unroofed, undermined, or flooded. Over 11,000 hectares of rice, crops, and other plants were inundated, flattened, or buried, and thousands of livestock and poultry were killed or swept away. Many residential areas were cut off, while key transport routes, schools, health facilities, irrigation works, and power and water systems were all seriously damaged. The total estimated losses from the two consecutive storm events exceeded 3 trillion VND.
According to the Vietnam Fatherland Front Committee of Cao Bằng province, 12 suspension, concrete, and rural bridges were damaged or washed away, disrupting transport and severely affecting the lives, education, and livelihoods of residents, particularly in Nguyên Bình, Trðá»Âng Hà, Trùng Khánh, Thành Công, Minh Khai, and Khánh Xuân communes, where many bridges collapsed or sustained major structural damage. Access roads to several hydropower plants were also damaged by landslides, with the Bình Long hydropower area being the most severely affected. Several Special National Historical Sites in the province were damaged, including the Pác Bó Special National Historical Site and the Trần Hðng ÃÂạo Forest Special National Historical Site.
In Hanoi, heavy rainfall beginning on 29 September, particularly on 30 September, caused severe flooding; students were stranded at schools due to torrential rain. On 6 and 7 October, heavy rainfall returned, prompting the Hanoi Department of Education and Training to suspend classes, with many schools adjusting teaching schedules accordingly. Flooding continued across the city, including along ThÃÂng Long Boulevard, where Coast Guard officers assisted residents in moving stalled vehicles. In Trung Giã commune, northern Hanoi, near the Thái Nguyên border, rising waters of the Cầu and CàLá» Rivers caused flooding that isolated more than 2,300 households and resulted in losses worth billions of ÃÂá»Âng. The HanoiâÂÂThái Nguyên railway line was severely damaged by a landslide in the area.
In HanoiâÂÂs vegetable- and flower-growing zones, such as NháºÂt Tân, Mê Linh, and Tây Tá»±u â known as major horticultural areas of the capital â severe losses occurred as floodwaters from the Red River, following Typhoon Bualoi, inundated farmland. After prolonged flooding associated with Matmo, most flower crops were destroyed, leaving many farmers without stock to sell. In ÃÂa Phúc commune, about 980 hectares of autumn rice were submerged, including nearly 550 hectares within the paddy area and over 430 hectares outside the dyke system. Numerous canals, drainage sluices, and irrigation works suffered landslides or localized damage, along with extensive property losses for local residents.
In Tuyên Quang province, the remnants of Typhoon Matmo brought widespread heavy rain, resulting in one death and significant damage to housing and transportation infrastructure, severely affecting daily life. On the morning of 8 October, the welcome gate of ÃÂá»Âng VÃÂn commune center â a cultural landmark inaugurated in November 2024 â collapsed due to a landslide. The structure, valued at over 1.5 billion VND and funded entirely through social contributions, had been regarded as a local tourism highlight in the northernmost region.
In the North Central Coast, Thanh Hóa province reported, as of 1 October, more than 17,000 flooded houses, including 1,456 homes damaged. The dyke system sustained 13 incidents involving erosion, seepage, surface subsidence, and slope failures; notably, a 20-meter breach occurred on the right bank of the Thá» Long River in Các Sán commune.

Lạng Sán received 2,000 tons of rice from the national reserves to support residents affected by prolonged flooding and storm impacts.
Prime Minister Phạm Minh ChÃÂnh also approved an additional 400 billion VND in emergency funding from the Central BudgetâÂÂs 2025 contingency reserve to aid four northern provinces in recovery: Thái Nguyên received 250 billion VND, Cao Bằng 80 billion VND, Lạng Sán 50 billion VND, and Bắc Ninh 20 billion VND. This was the second financial aid package issued within less than two weeks for areas severely affected by the disasters. The Ministry of National Defence deployed two helicopters from Air Regiment 916 (Hòa Lạc Air Base) and one helicopter from Army Corps 18 to transport Deputy Prime Minister Trần Há»Âng Hàand a working delegation from Gia Lam Airport on 8 October, carrying relief supplies to Lạng Sán province. Hðng Yên province also contributed 1 billion VND to assist Lạng Sán in overcoming disaster impacts.
In Trung Giã commune (Sông Công and Thành Công hamlets) of Hanoi, on the morning of 12 October, hundreds of officers from the Hanoi Police Department and local residents worked together to pump out floodwater, remove mud, and clean houses and furniture.
Acecook Vietnam JSC donated 3,700 boxes of instant noodles. On 2 October, the Vietnamese Fatherland Front Central Committee launched a nationwide appeal for contributions to support recovery from Bualoi and subsequent flooding. By 17 October 2025, individuals, organizations, and enterprises had pledged around 1.025 trillion VND in donations.
On the afternoon of 13 October, at Noi Bai International Airport in Hanoi, the Department of Dyke Management and Natural Disaster Prevention and Control under the Ministry of Agriculture and Environment received a shipment of emergency relief supplies from the Japan International Cooperation Agency (JICA) to assist residents of Bắc Ninh Province affected by flooding. This marked the first international relief delivery for Vietnamese localities impacted by Typhoon Bualoi and Typhoon Matmo. The shipment included 40 water purifiers, 5,100 blanket sets, 1,000 plastic water containers, and 50 multi-purpose plastic sheets. On the night of 14 October, also at Noi Bai International Airport, Australian Deputy Ambassador to Vietnam Renée Deschamps, Deputy Director General of the Department of Dyke Management and Natural Disaster Prevention and Control Nguyá» n Trðá»Âng Sán, and Vice Chair of the Bắc Ninh Fatherland Front Committee Thái Hải Anh jointly received a humanitarian aid shipment from the Australian Government, intended to support households and communities severely affected by the storms and floods. According to the Australian Embassy in Vietnam, the Australian Government provided A$3 million (approximately 51 billion VND) in humanitarian assistance to help Vietnam respond to widespread flooding and storm impacts across northern and central regions. The Embassy of South Korea also announced that the South Korean government had approved a US$1 million (approximately 25.4 billion VND) humanitarian grant to aid VietnamâÂÂs disaster recovery. In addition, the ASEAN Coordinating Centre for Humanitarian Assistance on Disaster Management (AHA Centre), the Embassy of Canada, and several other international organizations contributed relief assistance. As of 16 October, the total value of international aid reached US$5.7 million.
The Ministry of Agriculture and Environment of Vietnam assessed the 2025 Northern Vietnam floods as one of the most severe natural disasters in recent decades, characterized by successive major floods over a wide area. The ministry noted that multiple hazardous phenomena occurred almost simultaneously, including major, record-breaking floods, flash floods, and landslides, all of which caused severe loss of life and property, as well as extensive damage to dykes, reservoirs, and essential infrastructure. A Deputy Minister acknowledged that response measures to the historic flooding had remained largely reactive, forecasting of extreme rainfall and exceptional floods was still limited, and overall disaster resilience needed improvement.
The heavy rainfall on 30 September in Hanoi prompted discussion over the adequacy of urban drainage systems and infrastructure investment. Some experts observed that rapid urban expansion and the filling of former low-lying areas for construction â particularly in Hanoi and Thái Nguyên â had worsened flooding impacts. Associate Professor Nguyá» n Ngá»Âc Trá»±c suggested that Hanoi should establish and implement a comprehensive urban flood risk management framework, both for the capital and for other flood-prone cities. The Hanoi PeopleâÂÂs Committee directed agencies to review and expedite water supply and drainage projects, including the Liên Mạc Pumping Station; chairman Trần Sỹ Thanh stated that the flooding in Trung Giã and ÃÂa Phúc communes served as a practical test for the operation of the two-tier local government model, which had come into effect nationwide on 1 July 2025.
