Myanmar is Bangladesh's eastern neighbour. Bilateral ties with Myanmar are generally good, but some tensions exist between the two countries. This is due to border disputes and the presence of over 270,000 Rohingya Muslim refugees in Bangladesh from mainly-Buddhist Myanmar. As a result of bilateral discussions, and with the cooperation and assistance of the UNHCR, most of the Rohingya refugees have now returned to Burma. As of 2000, about 22,000 refugees remain in camps in southern Bangladesh.
