They have the workforce, but the technology people are mostly Europeans and Americans. Therefore, things are not that clear. In terms of funding, a single country cannot cope with such a project. One needs contributions from many countries, which is already in place at CERN.
I personally hope to have it happening. The location does not really matter. And as said in my answer to the comment of @gentleshaid, there are enough project to reasonably have one in China (the electron-positron version of the collider) and one at CERN (the proton-proton version of it). On the other hand, having two big collider projects... I don't know whether this is realistic.
For the moment, the only certainty is that things are unclear.
This answers all my questions.
Cool! :)
