I'm pretty sure they're stirring up trouble in xinjiang also. Pitting ethnic minorities in hard to defend mountainous border regions against central government is a standard divide and conquer empire tactic. The British Empire used it a lot in Asia, for instance.
Dictators almost always have secret police, and domestic espionage agencies in every corner.
This is why I do not subscribe to notion that Western spies are trying to stage revolutions in repressive regimes for a simple reason that they can not.
Most of Latin America had had a US backed coup at some point in its history. Many very successful. Pinochet, etc.
US only ever managed to use staged coups to unseat civil governments, and failed miserably with tougher targets like real totalitarian regimes.
The only notable exception I think was Noriega, who was a joke of a dictator, and possibly even put in power with American help in the first place.
The only two cases that I’m aware of where the US clandestinely toppled a foreign government were Chile and Iran - and apparently even the Iranian operation was mostly driven by the British secret service. And by all accounts, Chile was more of a nudge than a push.
And that’s just one example of one mineral. There is the notion of the “resource curse” —countries rich in natural resources often stay poor because why develop a modern economy when you can just become a warlord and force children to mine diamonds or cobalt for you? The flip side of this is the part where we in the developed world don’t like to think too much about where these basic resources come from.
