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. The trade relationship has been, to put it mildly, strained. The Chinese leadership has not responded to quiet diplomacy. It is, therefore, time to reconsider our relationship and break off diplomatic relations with China. - The Madison Daily News
