Also, did you even read and understand the PDF you posted? It was the US governments deal with the Taliban. So under Trump they already recognize it was the Taliban who would rule Afghanistan.
Even before the announcement it was already being mentioned here that it will be China that will be the most likely ally of the Taliban.
