We know several things:

1) like Saudis brutally killing Kashogghi, the imprisonment of 1 million Uighurs is a game-changer - whereas we all questioned the Belt & Road initiative, this one is simply evil, especially for the younger more human-rights/diversity-driven set. Curiously enough, Trump's trade war with China looks to be good timing but for wrong reasons, but could put the Chinese back on their heels for a bit - it's been totally cocky-time with Xi Jinping, who sees himself as another Mao, except without the veneer of socialism - just himself. The Chinese intrusion & building concrete "islands" around the Spratleys has also destroyed trust.

2) the Japanese fell on the ramparts of pouring concrete - a fetish that ground down the economy and took away their edge. The Chinese are doing a wonderful job of emulating - just keep building infrastructure that couldn't be justified profits-wise, but as a beacon to humiliate the West (yeah, they're still suffering over the Opium Wars and other western effrontery, little brother or slave inferiority complex). Which means Jinping's future-planning is based as much on symbolism as realities - delusions that seldom work out in practice.

3) Ironically to me, I think we need something like the Chinese global Belt and Road initiative - but not for the easier ports, but for internal growth, the places left behind, whereas absconding with all the ports is simply a way of conquering infrastructure economically, rather than providing a needed boost. Trains & roads? again, more infrastructure of questionable motive.

4) Hong Kong will not be forgotten. Beijing wants its cake, but not that simple - the Hong Kong experiment lives on.

5) China's salaries are sky-rocketing comparably, and that puts pressure to slow & reverse offshoring. How will China internalize growth rather than trying to push production & imports higher and higher? The world will have less demand for Chinese goods and services.

6) Again expect differences between Chinese tech dreams and actual delivery. For years China could build stuff, but not market it. There's also a big difference in the types of plough-ahead innovation China excels at, and that innovation that creates new services, breakthrough delivery, "something new". Note that the latter controls the patents, though for decades China's rigged the ownership scheme, making expats sign draconian co-share deals as price of entry to the market. No one believes China will play fair anymore, and this new skepticism will shape the future market. And with skepticism, the price of transactions increases, and Chinese trade is all about low transaction cost.
