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.
He's talking about kicking off WWIII to dethrone the US now. Nukes, all out strikes, cus he can't "stomach" seeing dead children anymore.
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.
This is due to their core deficiency. The West would like to do that to every country but they cannot succeed in strong societies, especially not in China. The Muslim problem is that they are too dedicated to their god and have allowed it to give them a false sense of security and lulled them into laziness. They should spend 30 seconds a day praying and 15 hours a day studying the sciences including physics, engineering, computer science, etc... Instead, they neglect the sciences while spending most of the day praying and talking about god, thinking that this will make him "forbid" the slaughter and defeat of Muslims. Because of this weakness, their societies are weak, and thus susceptible to American assassination and manipulation.
The height of Muslim power was when Salahuddin defeated the Christian armies over Jerusalem. When one of the other Muslim commanders said that all victories are the will of God, Salahuddin retorted, "God did not will these victories to the Muslims until I came."
This spirit of self-reliance instead of divine reliance is what they need to defeat Israel, but they do not have it. Iran's technological capabilities are the star of the Muslim world; any hope to return to Muslim glory lay in the emulation of Iran's fighting spirit, but even the Iranians are not clear-headed about who is friend and who is foe. So much more is needed.
