China fears 'Islamist terror attacks' from 'Uyghur militants' now that the Taliban controls Afghanis

2. The Wakhan Corridor is not a useful infiltration route for terrorists from Afghanistan to China

China's border with Afghanistan is at the eastern end of the Wakhan Corridor, a roughly 200 mile, steep sided, narrow mountain valley sandwitched between Tajikistan and Pakistan. It is very difficult terrain for transport, and probably not much moves there that China doesn't know about.

The terrorist route is north to Tajikistan and then east across the extensive border with China. Or even further north through Kyrgyzstan to China. Which is why the US has been attempting to destabilize the former Soviet republics in Central Asia since the collapse of the USSR.

Afghanistan is also the training base for terrorists from Chechnya and the rest of the North Caucasus working against Russia.
