Those negotiations are on the conditions that will have to be met before the United States will support China's admission. China is not even close to meeting any of the economic requirements that all other countries have met, but it has made very clear that it thinks it should be let into the WTO anyway. Once it was member, it would gain huge new trade benefits while at the same time it would be allowed to continue its current unfair trade practices. It would then not have any incentive to meet world standards on trade. It would continue to get richer at the rest of the world's expense, and especially the United States' expense, without making any reforms.
China runs huge annual trade deficits against the United States.
China is rapidly turning itself into a new superpower world menace with that American money. Some American businesses, and, to a lesser extent, some American farmers, have been benefitting from the trade with China, despite the huge imbalance. They have argued for a continuation and expansion of the United States' current trade policies with China, and they have urged the United States to refrain from criticizing any of the Chinese communist government's many abhorrent and dangerous policies. Most politicians have taken that advice, and none more enthusiastically and completely as President Clinton. China is a barbaric communist nation that may well pose greater dangers to the United States than any other country.
