The question is, whose tune is the PLA marching to? Xi Jinping is also the head of the military commission. Many here in India suspect that this was the Chinese way of testing Modi. If so, they picked the wrong guy at a time when the US and Japan are both courting him. One fallout is that a Chinese official media team coming to India for "interaction" with Indian media, suddenly had their permissions scrapped.
It’s possible that Xi is giving certain people in the PLA a long rope.
