What plate boundary exists to the east of bangladesh

To the east of Bangladesh, there is the plate boundary between the Eurasian Plate and the Indian Plate.

Explanation:

Bangladesh is a country located in the northeastern part of the Indian subcontinent. The country is located on the Indian plate, tectonically speaking, but on its eastern side it is where the Indian plate ends and the Eurasian plate starts. This actually marks part of the boundary between these two plates.

The plate boundary between the Eurasian and Indian plates is a convergent plate boundary. They push against each other and the plate boundary is between continental crusts. This has resulted in alleviating the crust around the plate boundary and creating mountain chains, most notably the largest mountains in the world, the Himalayas.
