China officially recognizes the Taliban: Hua Chunying MFA spokeswoman says at a press conference that "We respect the Choice of the Afghan people"
Embassy is staying, being treated not as a regime collapse but just a regular change of Government.
https://news.cgtn.com/news/2021-08-16/China-says-respects-Afghan-people-s-choice-amid-changing-situation--12LYPEBkpK8/index.htmlThere have been many comments in the west that China has a great interest in Afghanistan, that China is likely to fill the power vacuum left by the west, wants to invest in infrastructure there etc., but that is actually...well...not really the case.
There are some contracts for resource extraction (mostly stalled/abandoned, most notably Mes Aynak) and small scale infrastructure, but there aren't really substantial investments nor is there much of an interest in Afghanistan at all actually, besides for having a propaganda field day re the US for Saigon II. It not really remotely comparable to Iran or Pakistan for instance. China will retain cordial relations with the Taliban (like it did with the previous Regime) to ensure stability and avoid the reemergence of terrorism, but the Idea that there is really substantial "Interest" in Afghanistan is largely overblown, for better or for worse.
