I could see in extremis that the US might implement some sort of distant blockade on China to stop raw materials like e.g. Chilean copper ore, iron ore, oil, etc., if some arrangement cannot be agreed to keep the US supplied with RE products.They talked, but did not do it, about decoupling for so long that now Xi is telling them, that it's ok he will decouple instead.
Very considerate of Mr. Xi indeed
There is talk on Western Twitter sphere that this might be Japan oil embargo situation if enforced strictly by China (means that US could be forced to initiate war lol)
