A real mind blower would be China recocnizing undisputable right of Pakistan over Kashmir and a mutual defence aggrement. Whereby Chinese get the right to host their navy and airforce on Pakistani soil to counter India. Perhaps Pakistan negotiating another overseas Chinese presence in Afghanistan to counter Indian presence in Tajikistan.
Building a "NATO" style asian defence leauge with China, Pakistan and Afghanistan as founding members followed by an offer to all "-istan" countries as counter measure to India and Russia.
The rapid "chinesification" of PA arsenal gives a strong hint towards such leauge in future. Wherby PA operates a two winged army one with Chinese goods and another with western goods.
