As per you? What's likely trajectory of US China relations in tangible terms in next 30 years? My guess follows in thread below

1. Wall street and US tech majors will get major access to Chinese markets
2. China-Us trade will become free-er but also more balanced than today. Us will diversify supply chains but not to that great extent. China will remain main trading partner by miles

3. China will fix yuan at a slightly overvalued rate a la plaza accord. Win win in short to medium run for both countries
4. Us and China will enter into mutually agreeable spheres of influence in Asia. Some differences will remain but not intractable

5. China will give the appearance of making big concessions on climate change. This will be one of the first steps likely to happen very soon under a Biden administration that will set the road for a detente

6. China will modernize its military and strengthen it much more in the next 30 years

In other words US elites will largely be coopted and China will increasingly give assurance that interest of US elites is not threatened by a rising China. US will do enough to ensure China isn't threatening it but not actively work to hinder its rise

A lot of 1-5 will happen in next 10 yrs itself
