I will add to your list, they need to control their greed, stop claiming everything they want theirs, stop acting like a big bad bully to smaller countries. They need to take care of their own problems instead of causing problems to others.
They have occupied some regions in Indian border. It was the previous Indian government's fault too for not taking action against them. Now when the new govt demanded it back and our PM did not support some of their projects, China is supporting Pakistan indirectly. India-Pak share complicated relationship. Pak wants to occupy Indian border, they keep planting bombs killing soldiers. We can never forget 26/11. China is taking advantage of that.
World is in danger!
