Europe is a very important component there as well. The EU plus wider Europe is an economy the size of the US, so a very substantial part of the global economy to say the least. It remains to be seen exactly how Europe will go in regards to dealing with China. I think that will have a considerable impact on the extent of China's economic isolation, if that is to be (assuming they don't liberalize access to their economy and end various negative trade practices). Obviously most of the major economies of Europe are increasingly debating how to handle China. In terms of potentially limiting China's access to their markets, limiting the ability of China to buy their companies, forced technology transfer, and so on. The outcome of which way/s Europe breaks on this topic is an interesting wrench in the whole thing (eg Western Europe might put up further defenses, while parts of Southern Europe and Eastern Europe + Russia may go more heavily with China). If you're eg German automobile makers or Italian & French fashion / cosmetics companies (LVMH is drowning in Chinese sales presently, making Bernard Arnault worth nearly $100b), you desperately want to maintain full access to China at low tariffs.
