Restore the nuclear agreement with Iran, sanctions on Russia and China.
With China specifically, I would frankly encourage moving manufacturing to other countries in Asia, including Vietnam and India. China is actually no longer the cheapest country in the region to send manufacturing jobs to. Manufacturing in third world countries is an unavoidable thing at this point, so instead encouraging putting those jobs in countries that are, well, ruled by less shitty governments than the CCP would be a better idea.
Otherwise, I do actually think colaborating with blocs like the EU to economically isolate China is the least damaging/violent way to remove the CCP from power, but last time I suggested that it resulted in a rather heated argument that ended up getting me temp banned, so I'm wary about getting too deep into that again. I think the CCP being removed from power permanently is a good thing for both the world and the people of China simultaneously. Aside from the well-known extreme authoritarianism the CCP indulges in and previous and current attempts at cultural and actual genocide, for all its talk of nationalism and whatnot the CCP has at times either actively tried to destroy China's pre-communist culture and history or shamelessly exploit it, and I'm not sure the party really cares for the country's rich history other than being a tool for exploitation. Problem is, the question of how to remove them from power is really hard and virtually impossible without causing some part of the Chinese population to suffer, which fucking sucks.
