I don't think they will save us, but rather that they will try to fight over geopolitical and economical spaces in order to further extend the reach of their own power. This practically means creating a separation between America and Europe. What I was trying to say is that if the Chinese aren't willing to fight for Taiwan, it's very unlikely that they will go for a confrontation against America over Europe. If that's the case a bipolar order is about to return, where Europe is the official feud of America, Russia is the official feud of China and Africa and South America is where they will try to get as much advantage as possible.
