Is This the Moment for China to Show Its Leadership?

This week has been particularly difficult for it, i think, with russia's mobilization and the holding of the referenda. The way that it's tried to deal with it really is to emphasize that it wants a negotiated solution. It does repeat the thing that we associate with china so firmly, the idea of support for state sovereignty,. So how does it compensate for that very strong statement of support for tradition or state sovereignty?
