In Recent Years, United States Policy Toward China Has Been

In recent years, United States policy toward China has been confused. China is the world's most populous country and a major military power, and has become an increasingly valuable trading partner. It has been the view of Presidents, therefore, that it is in the United States interest to remain on good terms with the Beijing government. However, the human rights situation in China shows few signs of improving. In addition, the end of the Cold War has made the political logic of a close relationship with China less compelling.

C) we have few allies in the world who can be trusted consistently
D) alliances can now be forged solely on the basis of shared economic interests
