The U.S. has said repeatedly that peace between both sides of the Taiwan Strait is "in the interests of the United States" and it welcomes peaceful development of cross-Strait relations.

It has also said, many times, that it hopes both sides of the Taiwan Strait strengthen their dialogues and interactions in economic, politics and other areas and establish a more positive and stable relationship.

However, while the entire picture of the cross-Strait relations became brighter, the U.S. made a new decision on an arms sale to Taiwan.

The decision not only runs counter to the mainstream will of pursuing development and cooperation among the people on both sides of the Taiwan Strait, but also exposes the U.S. usage of double standards and hypocrisy on major issues related to China's core interests.

China and the United States, both world powers, have broad common interests and important responsibilities in a series of major issues related to peace and development of each nation and all mankind.

Despite all the ups and downs over the past 30 years, the overall China-U.S. relationship has maintained forward-moving development, while common interests and cooperation between the two countries have continuously expanded.

That not only brought concrete benefits to the peoples of both nations, but also contributed to world peace and development.

Obviously, the current good situation in China-U.S. relations is a result of no easy effort, and both nations need to take extra care of it.

The global financial situation has been improved, but uncertainties remain.

It requires China, the United States and the international community as a whole to make continuous efforts in a coordinated way.

China-U.S. cooperation is indispensable in solving counter-terrorism, nuclear nonproliferation, climate change and other major international and regional security issues.

The age of our times needs healthy, stable and developing China-U.S. ties.

Defying such a historic trend and making such a wrong decision that undermines China's core interests and the overall situation of China-U.S. cooperation, can't be viewed as a wise action by any responsible government, no matter if it was influenced by residue of the Cold War mentality or the pressure of certain special interests.

China recently has made several solemn representations to the American government on the arms sale issue, asking the U.S. to fully assess the serious damage caused by the sale and to take China's concerns seriously and stop the transaction.

Otherwise, the sale will cause seriously negative effects on China-U.S. exchanges and cooperation in important areas, and ultimately will lead to consequences that neither side wishes to see.

If the U.S. continues to ignore the solemn position made by China and is determined to make the wrong decision to sell arms to Taiwan, it ought to take all the responsibilities for any serious consequence caused by such a decision.
