I believe neither you, nor most of the users here understand the core of the problem you have. The idea of "cooperation" is a mistake in your situation. When you have to deal with Israel you have to deal with the whole of the West. Buying 500 fighter jets from China(which of course is impossible, the Chinese will never sell you something that puts their trade with the West in danger) doesn't work for you. Nor the idea of buying AD systems. Everything will be destroyed if not in a few days, then in a few weeks. You need to produce everything by yourself, you need a closed cycle of everything. And you don't have it, you don't have the resources, and you don't have the strategic depth to fight a conventional war against the Western military machine. There was only one country and a system that maybe was able to go toe to toe vs the West, but it is a long time gone.
Second of all, you do not understand what China is. Pakistan - China cooperation is not gonna work for you, nor for anyone who tries to fight the Western war machine. China is pretty much part of the West. China benefits from the Western wars. It gives them a chance to blackmail the countries that the West is sanctioning, they are conquering markets and buying cheap oil from them. But. Pakistan is just a tool for containing India, no one really cares what China and Pakistan do. But if you add here Iran or Russia for example it's a whole different picture. The Chinese won't move their fingers if there's a minimal chance to be sanctioned by the West. They won't do anything that puts their trade with the West in danger, forget about it.
The only way for you to cooperate with China is to become completely irrelevant in the eyes of the US and Israel. Which in your case it probably means a regime change, Western countries all around your oil and mineral resources, and a pro-Western government. But then again, this cooperation will be done with the West, not with China.
