As you know,most of us consider that China and Pakistan are friends .But in my opinion,Pakistan is only a useful tool for China to counterwork India,just like the relationship between USA and Corea.So,if Pakistan lost it’s value,it will be a block for China to become a super country.

China's ruling communist party thought is, China's power should radiate from inside to outside in layers of circles, as you go to outer side the power should diminish. Pakistan, North Korea are in the second circle of power.
