BO’AO, China — The senior leadership of the Chinese government increasingly views the competition between the United States and China as a zero-sum game, with China the likely long-range winner if the American economy and domestic political system continue to stumble, according to an influential Chinese policy analyst.

China views the United States as a declining power, but at the same time believes that Washington is trying to fight back to undermine, and even disrupt, the economic and military growth that point to China’s becoming the world’s most powerful country, according to the analyst, Wang Jisi, the co-author of “Addressing U.S.-China Strategic Distrust,” a monograph published this week by the Brookings Institution in Washington and the Institute for International and Strategic Studies at Peking University.

Mr. Wang, who has an insider’s view of Chinese foreign policy from his positions on advisory boards of the Chinese Communist Party and the Ministry of Foreign Affairs, contributed an assessment of Chinese policy toward the United States. Kenneth Lieberthal, the director of the John L. Thornton Center for China Studies at Brookings, and a former member of the National Security Council under President Bill Clinton, wrote the appraisal of Washington’s attitude toward China.

In a joint conclusion, the authors say the level of strategic distrust between the two countries has become so corrosive that if not corrected the countries risk becoming open antagonists.
