Chinese had only one reliable strategic partner in last 70 years. That Pakistan, so they don't think from pti mindset. They had, they have and they would continue this strategic partnership with state of Pakistan and Pakistan armed forces. In 90s when pro american Benazir was in power, they had more concerns. but still in that period , they had supplied M-11 surface to surface missile to Pakistan armed forces for strategic launch of nuclear weapons.
So please don't bring neighbors into internal issues, keep those power rift issue inside the home. Thanks
