Thailand has not established agreements withCambodia andVietnam, who also have maritime territory in the Gulf of Thailand, leading to conflicts.[4] It also has not established a treaty with Malaysia on their gulf waters; however, theMalaysia–Thailand joint development area was established for both countries to jointly exploit the resources in the area of their overlapping claims.[5][6]
Cambodia claimed the islandKo Kut (Koh Kood).[7] However, the French colonial administrator François Marius Baudoin (1867-1957) made an official map titledCambodge Physique in 1927.[7] This map features the maritime border between Cambodia and Siam (Thailand).[7] Ko Kut is within the Siamese maritime territory.[7] The black demarcation line is 240 degrees to the south of the townKhlong Yai inTrat Province, Thailand, and the town Phumi Cham Yeam in Cambodia.[7]
