This is why Pakistan must show flexibility on the immigration especially from China and North Muslim dominated lands.
China needs Pakistan too so Pakistan should not field 100% blindly for China like Musharraf did for USA. Pakistan needs to show little flexibility to protect the interest of Muslim people in China and the rest of Northern Asian lands in the name of Islam.
We need to remember that China is not brotherhood nation of Pakistan. China is helping Pakistan because both have same goals; India/USA/Israel.
Once the goal is achieved, then i am certain Pakistan vs China will be next since by then Muslims in China will be under threat as China continues to posses its communism against the wills of Muslim people.
