When we created Bangladesh, Pakistan had alliance with US, Europe and gulf, but nothing worked out. If India decides to annex BD or curve out Hindu Desh out of BD, Chinese alliance will not work. It won't take much effort for India to neutralize China even diplomatically. China was much closer friend of Pakistan but couldn't come to rescue Pakistan in 1971. China couldn't hold it position in Himalayas against India and agreed to our terms and conditions. We are expanding our foot prints in south China sea China is not in a position to message with India and certainly not for the sake of BD. As I said earlier, India is not interested in Pakistan or BD but certainly, we are interested to POk and curving out Hindu Desh and northern BD to thicken our Chicken neck.
