BEIJING - Gary Locke, the newest US ambassador to China, promised on Sunday to promote bilateral cooperation and understanding between the two countries.

Acknowledging challenges in the "important and complex diplomatic and economic bilateral relationship" between the two countries, Locke said he looks forward to working with the Chinese government to expand bilateral cooperation and collaboration.

He made the remarks at a press conference held on Sunday afternoon, his first public appearance since arriving in Beijing on Friday evening. Locke's wife Mona Lee and their three children accompanied him at the conference.

Speaking about the things he hopes to accomplish over the next several months, Locke said the most important thing will be "to promote stronger and better understanding between the US and China."

"This must be done so that more people in the United States understand China, its history, its contributions to world civilization, its challenges and the amazing progress China has made in such a short time," he said.

Locke also stressed China's "unique history, culture, and philosophy", which he said must be understood if the two countries wish to forge a more cooperative relationship.

Locke, a Democrat, was elected as Washington state's 21st governor in 1996, becoming the first Chinese-American governor in US history. He won reelection in 2000. President Obama nominated Locke as Commerce Secretary in February 2009.
