In the Chinese media I've read about this, the CIA usually isn't accused directly. Rather, they cite a Washington Post article [1] where Allen Weinstein, co-founder of the National Endowment for Democracy, says "a lot of what we do today was done covertly 25 years ago by the CIA." Then they argue that the NED's funding of various political groups in Hong Kong [2] is essentially a CIA operation.

Personally, I think that's a lazy argument trying to link the CIA (known bad) to the NED (therefore also bad). On the other hand, it does mean that US government organizations are picking favorites to provide with funding in order to influence the politics of foreign countries.
