This talk if happen, won't have any tangible result. China think, or at least, pretend to think the US is the problem here. But no, Israel is the main problem here. Under the hardline ultranationalist Netanyahu, Israel won't give anything to the Palestine. I would even be surprised if Israel accept this talk. At this point, Palestine is a lost cause, even the islamic countries today couldn't give a crap about Palestine. They only pay lip service.
