Some Southeast Asian countries commanded important waterways and controlled costly trade routes in this way Southeast Asia’s geography contributed to the region’s economic development.

Explanation:

Usually, all of Southeast Asia lies between the tropics. Thus there are similarities in the atmosphere just as plant and creature life all through the area. Temperatures are commonly warm, although it is more relaxed in suitable country territories.
