Re: Well, that does it for Western companies investing in China
The fact that they're publicly appealing in this way, might suggest that they haven't got anywhere in private appeals to whoever they know in the Party. Xi Xinping, in particular, has been playing the nationalist card quite a lot in order to maintain some sort of popularity. And of course that can be a double-edged sword, as other people can then appeal to that same sentiment, and use it to put pressure on the government to back them in any dispute with those nasty foreigners.
China has so far heeded the example of Russia, where foreign companies barely bother to trade now, because they know they'll eventually get their stuff stolen. And so they don't have an independent judiciary either, but have been careful not to just randomly steal all the foreigners' stuff, so that they leave and slow China's growth. Hoping that nobody will notice a bit of intellectual property here and there, so long as the profits are good enough.
But China are currently shedding their caution on the international stage. They've made a lot of assertive moves of late, so maybe the Communist Party are feeling confident that they can do what they like?
Personally I think this is what will happen. Either through a feeling that the decadent West will be easily crushed, paranoia that we're out to get them or fear that China's troubles are becoming so great that only a bit of gambling on foreign adventurism will keep Xi in power - I think relations with China are about to take a decided turn for the worse - and that's going to lead to quite a big change in our economic relationship - which I suspect will lead to some onshoring off work that went to China and a lot of nice work moving to Vietnam/Indonesia/India.
