Burma, officially the Union of Myanmar, is the largest country by geographical area in Indochina. The country is bordered by China on the north-east, Laos on the east, Thailand on the south-east, Bangladesh on the west, India on the north-west and the Bay of Bengal to the south-west with the Andaman Sea defining its southern periphery. One-third of Burma's total perimeter, 1,930 kilometres (1,199 mi), forms an uninterrupted coastline.
Yangon is a former capital of Burma and the capital of Yangon Division. Although the military government has officially relocated the capital to Naypyidaw since March 2006, Yangon, with a population of over four million, continues to be the country's largest city and the most important commercial center. Yangon's infrastructure is undeveloped compared to those of other major cities in Southeast Asia. Yangon has the largest number of colonial buildings in Southeast Asia today.
