Not much space TBH AND PRC is unlikely to enable trade deficit with other producers like US/west to support export led growth. And reality is at PRC scale, "only" exporting 20% (i.e not even doubling down on exports) of GDP is enough to satisfy world demand in some sectors. IMO PRC fine with relegating lower end production (already happening) but will be just as protective as US/west on high end / high value (strategic) production.

What PRC does offer countries that want to catch up is access to cheap capital goods and cheap energy infra. Something PRC had to pay premium for while climbing ladder. It will be up to respective countries to arbituage accessible PRC capital and global demand to build up their industrial base... while opportunity lasts. Issue is we're in era where labour saving technology = more difficult to uplift via mass manufacturing employment and potential for export led growth is going to be increasingly limited as surplus importers try to reconfigure their own trade blocks.

But on the other hand 80% of the world , well 60% excluding PRC is consider middle income and poorer. So there is still substantial room to increase global consumption and accomodate new entrants, especially in non strategic / non zero sum sectors, it just won't be easy. Which is ultimately the limitation, a lot of underdeveloped countries don't have much competence in nation building and no ones going to do it for them. In strategic sectors, i.e. sectors where most countries can't support indigenously, or would take generations to build out (like having your own 200k aviation base that need 300 million population bloc to support), what PRC is going to offer is cheaper access relative to western incumbants. Hence PRC and west fighting zero sum in these sectors, with PRC trying to wrestle away western share, and west trying to protect their share. But the result should be more choice, cheaper choice.

IMO that's the cynicism behind PRC strategy, they will sell countries the tools to uplift themselves on the cheap, expecting most can't, while offering those that couldn't fallback/access to unparallely cheap goods, because PRC will simply have stupendous competitive advantage from being able to coordinate a lot of talent and a lot of robots across a lot of sectors linked by a lot of supply chains.
