Southeast Asia is a region geographically located between India and China, stretching from Myanmar to the Philippines and Indonesia. It has a population of over 500 million people and has long been an important crossroads for trade routes between Asia, Europe and the Middle East. The region experienced influence from Hinduism, Buddhism, Islam and Christianity due to its position along major trading networks. It was referred to as Southeast Asia during World War 2 when Japan occupied the area, and the term became widely used during the Vietnam War in the 1960s-1970s.
