Because we are not going to damage our relations with Myanmar just cuz of Bangli and Bangladesh. Pakistan was supporting Rohingya and Bangladesh until we were blind in love of umma chumma.

Rohingyas are not anything to do with BD apart from the fact they seeked refuge in BD.
BD stance on Kashmir is nothing to do with them.
