The U.S. government has repeatedly made it clear that it would welcome China’s entrance into the world arena as a power. However, a series of issues since the beginning of this year, particularly Washington's stance on the U.S.-South Korean joint military exercises and the South China Sea issue, have made the world think: Is the United States ready to recognize China as a power on the world stage?
It is easier said than done for the United States to adapt itself to China's development. Lip service is far from enough to boost the development of Sino-U.S. relations. If Washington cannot find a way to recognize and accept China's peaceful rise onto the world stage, bilateral（双边的） ties will be like a roller coaster full of ups and downs. However, no one would like to see the negative effects rocky relations would bring to China, the United States and possibly to the world as a whole.
U.S. Secretary of State Hillary Clinton has urged China to play a greater role in solving the world's economic, environmental and political problems. She said global issues could not be solved by the United States or China alone, but without participation of the two countries, no problems would likely be solved. Washington has realized that the United States' global interest can be maintained only through changing the way it deals with China.
The Obama administration released positive signals in its relations with China, which have been interpreted as the United States showing its intention to change the traditional strategy of engagement and containment（遏制）. As a matter of fact, the general direction of Sino-U.S. relations provides a foundation on which the United States can base its foreign policies and is more complicated than an adjustment in real conditions. Issues such as arms sales to Taiwan, Google censorship, RMB exchange rates as well as finger-pointing about economic responsibility show Washington still seems confused and inpatient about relations with China.
The relationship between China and the United States is the most important and complicated bilateral relationship in the world this century. The development of Sino-U.S. relations will affect world peace and stability, especially in the Asia-Pacific region. Ian Bremmer, an American political scientist specializing in U.S. foreign policy, said, "America and China will have more than ever to gain from closer political and commercial ties, and must take steps to avoid a Cold War, or worse."
In that circumstance, the United States needs both wisdom and determination to recognize and accept China, a country that is totally different from its own, as a power on the world stage.
