Na-sa-ka or Border Affairs Security Unit Chief, ex-General Khin Nyunt, says "Muslims from our country Myanmar have been fleeing to Bangladesh". (not Bengali coming in to Myanmar from Bangladesh)
Burmese language Interviews with ex-General Khin Nyunt contain a wealth of information. For instance, the military's strategic plan includes raising the country's population up to 100 million as the country is sandwiched between China and India while the government has singled out Rohingya Muslims and subjected them to various birth control and population control measures on the basis of their ethnicity. No other ethnic or religious group has been subject to a policy of population, marriage and birth control, hence a genocide. Further, Khin Nyunt talked about the fleeing of Muslims from Rakhine state to neighboring Bangladesh, not the other way around.
