I think the only way this is going to work is to continue investing in China. Play their game, call them out on foul play and punish China on a case-by-case basis. As the Chinese population becomes even more united, rich, educated, we have to hope that China naturally evolves towards a more open form of government and economy. It’s already making massive progress compared to where it was before.
In recap, this will be a long process of challenge and play. Any extreme action such as further or completely isolating China is not only extremely unlikely to even be possible, but also unproductive.
