Hmm....Inter-anglo regional rivalry? Better cultural exchanges between the English speaking world and China? Commerce (U.S. has been the main beneficiary of free trade, although some would think otherwise)?
I think it is the high level of academic and cultural exchanges because nowhere else can you find better analysis of China than in the English speaking world. Examples are here, here, here, here, and here. To name a few.
People back in China always wondered why study about China in the United States. It is because the studies are more rigorous.
