The ASEAN Multilateral Naval Exercise (AMNEX) is a regular naval exercise held by the navies of the Association of Southeast Asian Nations (ASEAN). It aims to build trust, improve skills, and make it easier for ASEAN navies to work together at sea. AMNEX focuses on non-combat areas like maritime safety, search and rescue, humanitarian assistance and disaster relief (HADR), and protection of the marine environment.
AMNEX was first proposed by the Royal Thai Navy and agreed at the 8th ASEAN Navy Chiefsâ Meeting in 2014. The first AMNEX (AMNEX-1) was hosted by Thailand in November 2017 around Pattaya in the Gulf of Thailand with the theme âÂÂProtection and Preservation of the Marine Environment.â The second AMNEX took place in the Philippines on 12âÂÂ15 May 2023, based in Subic, with both shore and sea phases and an ASEAN Fleet Review. The third AMNEX was hosted by Malaysia on 16âÂÂ22 August 2025 in Penang, alongside the 19th ASEAN Navy Chiefsâ Meeting (ANCM), an ASEAN Naviesâ City Parade, and an ASEAN Fleet Review.
