that's one more thing behind this. bro
they want to cover up their military strikes in Yemen and Syria which killed thousand of people and made many refuge to neighboring countries. That's much worse than what is happening in Myanmar. US will get at least 2 advantage from highlighting rakhine case in their media. such as 1) it will downplay what they are doing in Syria and Yemen and 2) it will also please their largest weapon buyers for what they did and 3) to disrupt China projects in Rakhine. many birds in one shot. if there was no rohingya problem , China projects can move forward with ease. now both China and Myanmar have to rethink about the project due to the region is unstable.
Please have some respect for the intelligence of your Chinese masters.
