I don't think China can do nothing about it even if they want to, Israel is a Middle East power supported by a group of much bigger Western powers. Sadly for the Middle East every single capable Muslim leader has been either killed or couped by the US, EU or Israel, from Mohammad Mosaddegh, Nasser, Arafat and so on, the list is big. That have leaved the Middle East trapped between elitists governments and monarchies who don't care for nobody else except their own wealth and extremists who only care about their own agendas. Perfect for Western companies and the military industrial complex. Bad for the people living there.
