I reckon the USA has left itself little room to maneouvre with China re any controversial political and economic issues that might arise. Why is this? It's on account of the foreign and economic policies that were instigated by George W, America's prodigal son, which have allowed the Chinese state to amass so many US dollars that it could plunge the good ole USA into deep recession by selling them at any time it deems such action necessary. As around 70% of world trade is attributable to the USA, the knock-on effect of China shedding its US dollars would be a severe global recession. Needless to say, Western politicians are not eager to talk about this in public as they will make themselves unpopular with their electorates by doing so.
China will continue to have many happy birthdays due to its bargaining power on the world stage as a result of its US dollar holdings!
