Do you have a reference for Chinese troops?
I see it bandied about on FR, but never a credible source.
I don't think that's real.
Lots of chatter 3 weeks ago, not much lately.

I think all they have done is sent air and naval assets, and I think they will just sit there, assuring that the EU-US think very carefully before doing anything, and also to remind Russia that they, too, are being watched. I can see China doing nothing beyond sailing in and then sailing out again once the terrorist organizations have been dealt with, simply acting as a suspended threat.
Here is an article presenting China’s guarded perspective:
