To do that, he'll need Chinese people in the 25-45 (prime consumption years) age bracket. They're not there.

Nixon got China to leave the 'Soviet Block' by offering 'most favored nation' status, same as was offered to countries devastated by WWII under the Bretton Woods Accords. That allowed those countries to sell into the US market, helping them rebuild their manufacturing - at the expense of our own manufacturing sector. Nixon's doing the same with China was a short-term brilliant move - that resulted in much greater impact on the US manufacturing sector. I suspect that it's because of the CCP being focused primarily on staying in power - which meant high employment at any cost, so not just exports, but supporting those export prices. The US, up through at least Clinton was focused on the hope of getting CCP cadres to relinquish power in favor of being rich - but those cadres chose power PLUS wealth. The US has since soured on the exchange - and tariffs are not an unreasonable response to CCP support of export prices. I don't expect those to go away, no matter who wins the US election. It's just a matter of how intelligently those might be applied.

More generally, Xi seems to have purged all the people who might have been willing to bring him bad news; I'm not sure he knows how dire the situation might be
