That is Pakistan's territory. China cannot infringe upon Pakistan's sovereignty.
It is Pakistan's job to eliminate terrorists and maintain local security. If Pakistan needs China's help, it should first authorize China.
I suggest that China, Pakistan, Iran and Afghanistan sign a four country cooperation agreement.
1. Establish a four nation joint law enforcement and security cooperation mechanism to jointly crack down on all illegal organizations in the region.
2. Establish a special fund to carry out unified integration planning and investment in the infrastructure of the four countries. Provide the same standard of water, electricity, highway, railway, gas and logistics services for this area. At the same time, the governments of the four countries need to commit to investing in education at no less than a certain proportion of GDP.
3. The four countries sign FTA, and the commodities of the four countries can freely enter each other's markets. And China can make some concessions. So that other three countries can make full use of China's market and have the ability to protect their enterprises.
4. Shelve the territorial disputes among the four countries and promise to talk about all disputes after 50 years.
China has signed similar agreements with Myanmar, Laos and Thailand. Because of the agreement, drug traffickers and guerrillas in the Golden Triangle have been eliminated
