It claims an EEZ of from its shores, which has long coastlines with the Andaman Sea and Strait of Malacca to the west and the Gulf of Thailand to the east, although all of its EEZ is limited by maritime boundaries with neighbouring countries.
Thailand's western sea territory stretches from the west coast of southern Thailand in the Andaman Sea and the Strait of Malacca. It shares treaty-defined maritime boundaries with Myanmar, the Andaman and Nicobar Islands of India, Indonesia and Malaysia.
Thailand has not established agreements with Cambodia and Vietnam, who also have maritime territory in the Gulf of Thailand, leading to conflicts. It also has not established a treaty with Malaysia on their gulf waters; however, the MalaysiaâÂÂThailand joint development area was established for both countries to jointly exploit the resources in the area of their overlapping claims.
Cambodia claimed the island Ko Kut (Koh Kood). However, the French colonial administrator François Marius Baudoin (1867âÂÂ1957) made an official map titled Cambodge Physique in 1927. This map features the maritime border between Cambodia and Siam (Thailand). Ko Kut is within the Siamese maritime territory. The black demarcation line is 240 degrees to the south of the town Khlong Yai in Trat Province, Thailand, and the town Phumi Cham Yeam in Cambodia.
