Southeast Asia is a sub-region of Asia, consisting of the countries that are geographically south of China, east of India.

Explanation:

Southeast Asia consists of two geographic regions: Maritime Southeast Asia and Mainland Southeast Asia. Mainland Southeast Asia comprises Cambodia, Laos, Myanmar (Burma), Thailand, Vietnam, and West Malaysia. These countries are culturally closer to India but ethnically closer to China. Currently, there are around 190- 205 million Buddhists in Southeast Asia, making it the second-largest religion in the region, after Islam. Thus, around 35 to 38% of the global Buddhist population resides in Southeast Asia. The region has been greatly influenced by the cultures and religions of India and China.
