Explanation:

Southeast Asia consists of mainland Indochina, Thailand and Myanmar, the Malaysian Peninsula, Indonesia, and the Philippines.

Eleven independent states with diverse populations and cultures are located in the area. More than 700 million people live in the region, around 8% of the world's population. In the north (Myanmar, Thailand, Laos and Cambodia) the culture of the majority is based on Theravada Buddhism. The south (Malaysia, Singapore, Brunei and Indonesia) is in a large majority part of the Islamic world. In the east of Indochina (Vietnam), Chinese culture is dominant and the Philippines have strong European and American influences. Although the culture of Southeast Asia partly originates from that of China and India, the region has its own different, cultural, social, religious and political traditions. Current Southeast Asia (with the exception of Burma) is an area of rapid economic growth, which is reflected in increased prosperity and rapid urbanization. The countries of the region are economically united in the ASEAN partnership, which is committed to more economic growth and peaceful cooperation.
