The first step is to recognize that this is not a technical issue but a political/diplomatic/military one. The second requirement for anything useful to happen is for Western governments to find some balls and start standing up to China in general. With those two changes in place, the groundwork is laid for a meaningful engagement on this specific issue. The likelihood of either happening is nil, so expect China to continue on its current trajectory. Eventually it will come down to whether Western corporations are willing to allow their governments to disconnect China from the rest of the world. Some will demand it, tired of incessant attacks; others will lobby fiercely against it, greedy for what they see as a profitable place to do business. Like so many issues in the West today, it will come down to one group of corporate lobbyists against another, both pushing for deeply suboptimal outcomes relative to what a sane world would have imposed years earlier.
