The USA first needs something of consequence to negotiate with China. One idea is for the USA to immediately move forward with deploying both nuclear weapons and defense shields in Japan, South Korea, and maybe even some other allies in the region. Even if secretly just posturing and sending over some boats with empty tubes for photo shoot and deploying some hardware but not the software and the car keys. China definitely won't want this on it's front door. OK then since you helped support this mess then help get North Korea to disarm and we'll pull the nukes out of your neighbors. This may give China a taste of what it's neighbors are feeling. Nobody likes looking down a barrel. Classic Bay of Pigs strategy - that's how Russia negotiated US nukes off their front lawn. They postured putting their own in Cuba until the USA caved in.
