With China"s growing influence over the global economy, and its increasing ability to project military power, competition between the United States and China is inevitable.【R1】______Most academic analysts are not so sanguine. If history is any guide, China"s rise does indeed pose a challenge to America. Rising powers seek to gain more authority in the global system, and declining powers rarely go down without a fight. And given the differences between the Chinese and American political systems, pessimists might believe that is an even higher likelihood of war. I am a political realist. Western analysts have labeled my political views " hawkish," and the truth is that I have never overvalued the importance of morality in international relations.【R2】______In fact, morality can play a key role in shaping international competition between political powers—and separating the winners from the losers. 【R3】______They were writing in the pre-Qin period, before China was unified as an empire more than 2,000 years ago. It was perhaps the greatest period for Chinese thought, and several schools competed for ideological supremacy andpolitical influence. They converged on one crucial insight; the key to international; influence was political power, and the central attribute of political power was morally informed leadership. Rulers who acted in accordance with moral norms whenever possible tended to win the race fpr leadership over the long term. Over the next decade, China"s leaders must play a larger role on the world stage and offer more security protection and economic support to less powerful countries.【R4】______Such competitionmay cause diplomatic tensions, but there is little danger of military clashes. That"s because future Chinese-American competition will differ from that between the United States and the Soviet Union during the cold war.【R5】______ China"s quest to enhance its world leadership status and America"s effort to maintain its present position is a zero-sum game. It is the battle for people"s hearts and minds that will determine who eventually prevails. And, as China"s ancient philosophers predicted, the country that displays more humane authority will win.A. Neither China nor America needs proxy wars to protect its strategic interests or to gain access to natural resources and technology.B. I came to this conclusion from studying ancient Chinese political theorists like Guanzi, Confucius, Xunzi and Mencius.C. This will mean competing with the United States politically, economically and technologically.D. Leaders of both countries assert optimistically that the competition can be managed without clashes that threaten the global order.E. But realism does not mean that politicians should be concerned only with military and economic might.
