WASHINGTON - US Secretary of State Hillary Clinton said Thursday that her country "is committed to the success of China" because it is also good for the United States.

The top US diplomat voiced the commitment in a congratulatory message to the Chinese public ahead of China's National Day on October 1.

"On behalf of President (Barack) Obama and the people of the United States, I congratulate the people of China as you celebrate your National Day this October 1," she said.

From Chinese President Hu Jintao's state visit to the United States in January to the successful third round of the US-China Strategic and Economic Dialogue in May, "the US has shown a deep commitment to this important relationship," she added.

"Together, our two countries are seizing this moment in history and developing the positive, cooperative and comprehensive relationship envisioned by our presidents," Clinton said.

"The United States is committed to the success of China, because a thriving China is good for America and a thriving America is good for China," she said.

She praised both the Chinese and Americans "for their hard work and ingenuity," adding that the two sides can find solutions to the most pressing global challenges through working together.

Clinton issued the message one week after Washington announced arms sales to the Chinese island of Taiwan despite Beijing's strong opposition.

Attending a reception on Wednesday at the Chinese embassy in Washington, US Deputy Secretary of State William Burns also struck a reconciliatory tone in his speech, saying that the United States welcomes the rise of a strong, prosperous and successful China that plays a bigger role in world affairs.

He also stressed that cooperation between the two countries would surely benefit both nations as well as the whole world, despite their differences on certain issues.

In another development, the US State Department announced Thursday that Kurt Campbell, assistant secretary of state for East Asian and Pacific affairs, will visit China on October 11 to hold the second round of the US-China Consultations on the Asia-Pacific with Chinese Vice-Foreign Minister Cui Tiankai.

The first round of the consultations, an outcome of the third US-China Strategic and Economic Dialogue in May, was held in June in Honolulu, Hawaii.

The consultations "reflect the shared commitment expressed in the joint statements of our leaders to build a positive, cooperative and comprehensive relationship," the department said in a statement.

Campbell will also visit Japan, South Korea, Brunei and Thailand and stop in Hong Kong during the October 5-11 Asian trip.
