evidence: The Andaman Islands (/ˈændəmən/) are an archipelago, made up of 200 islands, in the northeastern Indian Ocean about 130 km (81 mi) southwest off the coasts of Myanmar's Ayeyarwady Region. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. Most of the islands are part of the Andaman and Nicobar Islands, a Union Territory of India, while the Coco Islands and Preparis Island are part of the Yangon Region of Myanmar. [...] Most of the Andaman Islands became part of the Republic of India in 1950 and was declared as a union territory of the nation in 1956, while the Preparis Island and Coco Islands became part of the Yangon Region of Myanmar in 1948.[30] [...] Government [edit]Port Blair is the chief community on the islands, and the administrative centre of the Union Territory. The Andaman Islands form a single administrative district within the Union Territory, the Andaman district (the Nicobar Islands were separated and established as the new Nicobar district in 1974).
