I have no evidence that it would be otherwise.
Chinese actions are defensive, not agressive outside their hegemonic area.
Nixon agreed to Chineese hegemony and there has been peace in the area since. Taiwan may be at risk but I think the problems will be resolved peacefully. It remains to be seen if the Chineese will reign in North Korea. My guess is that the deal has been made and at some point arms will be twisted in Ponyang and all will simmer down.
Regarding fortifying the moon, perhaps. I have no reason to believe that is in the cards. China has so many internal problems that I place low probability on agression outside their turf.
