 Despite border (both territorial and nautical) tensions and the forced migration of 270,000 Rohingya Muslims from Buddhist Burma in 1978, relations with Bangladesh have generally been cordial, albeit somewhat tense at times.Many Rohingya refugees, not recognised as a sanctioned ethnic group and allegedly suffering abuse from the Burmese authorities, remain in Bangladesh, and have been threatened with forced repatriation to Myanmar.There are about 28,000 documented refugees remaining in camps in southern Bangladesh.
