The way China tried to hold the world hostage for rare earth minerals tells the underlying motives and thinking of the Chinese.   Creating islands to fabricate territorial claims is only another small part.   The only items they are looking for are raw resources, nothing finished unless they are interested in reverse engineering it (ask the Germans how they feel about their manufacturing cooperation now) and then cutting you out.   There is little good reason to assist China as it will only foster more of these selfish actions.   The next generation of Chinese (the one child families) are a bunch of spoiled idiots that don't understand the word 'no' as they are the focus of all the grandparents, parents, etc.  Once on the world stage these people with power will become a cancer to the world.
