There are multiple strategic intentions behind the illegal border crossing by the Indian army

Deflect domestic conflicts and please the United States to gain benefits. Of course, the United States also secretly strongly supports India in this regard. It interferes with China's development and attracts China's energy to make other neighboring countries of China prepare for the next round of mischief. It also hinders China's efforts in China. The construction of the Asian Road interferes with the One Belt One Road process. If China wants to settle the issue by crossing the border, they can join the One Belt One Road with high capital. Anyway, once you carry it on, it’s a competition to see who is tougher and who can have the last laugh.
