US has settled its "intervention objectives" in Afghanistan as pointed out in previous responses. Afghan Taliban have called on the US to release funds for Afghanistan and invest in Afghanistan but US have raised the issue of women rights in the present. China does not bother with these sentiments in comparison. USAID is working in Afghanistan but all else is frozen.
US wants to reduce its reliance on China for its manufacturing needs and build new partnerships in Asia to serve its interests. US will not attack OBOR projects, this is bad press and of little value. US will want to engage with China on some matters, keep the door open. How Elon Musk was able to open factories in China? American administration approved it because China is a big country and market in the end. There is posturing for public consumption in large part. US might check China in a conflict like it has done to Russia in Ukraine at most. Cold War is fought in a very calculative manner.
