The first time it was floated that China was definitely going to send its military to fight IS, etc., in Syria, I literally laughed it off and did so in public on the Internet. The second time it was floated, I didn't laugh it off but made clear to people that the situation had changed and that it wasn't possible to rule out the Chinese actually joining the fray. I said it was low probability at the time but should not be summarily dismissed, as it could be earlier. So now it's been claimed again. This time, I don't have to say one way or the other because the Chinese have made their current position quite clear if this news report can be trusted (and I have no reason right now to not do so).
The Chinese are not entering Syria militarily at this time.
