The extreme points of the East Asian Federation include the coordinates that are farthest north, south, east and west in the East Asian Federation, and the ones that are at the highest and the lowest elevations in the country. East Asia's claim to its southernmost point, Amboyna Cay, in the Spratly Islands, is disputed by five other nations, including the newly-reformed Republic of China, but is administrated as a part of East Asia's Pacific Island Territory.
