To correct, Rohingyas are not in Kachin state, but in Rakhine state. Rakhine state is in the southwest of Myanmar.Kachin is the North Burma. You are mistaking something here. And yes, Wa State is effectively a province of China. On paper they have 25k strong force, but they largely demobilised after the ceasefire. Though, if the ceasefire is broken, they have tube, and rocket artillery, manpads, even some armour.
