The difference is china is merely acting as a medator, a nutural 3rd party whos job is to 1) host the negotiations 2) help the 2 sides truly hear each other and come to a compromise. If you listen to what China says about this and how they interact with Russia its in keeping with this role, that all they want is to see the fighting end. The United States by dictating terms has forfitted there ability to fufill this role, China however has sugested nor offered any terms, only a table to talk at. If you really don’t want China it doesn’t have to be China, but they already have one side seated, and I would like to hear who else you would propose?
