The Chinese government is the one reasonable (i.e. excluding Trump) state actor that has the greatest leverage over both Iran and Israel. They can stop the wars in Gaza and Iran (and as a matter of fact in Ukraine) if only they were willing to exert their commercial force and enact embargoes.

China was Iran’s largest trading partner, buying up to 90 percent of its oil, according to the US-China Economic and Security Review Commission.

…and remains a top trade partner of both the US and Israel.

Of course they are also benefiting from the wars. Of course they also have their international crises. Yet, it seems to me that the benefit of peace to their economy and society is clear.
