The two sides also agreed to work to develop China's vast natural gas capacity.

U.S. and Chinese officials both spoke about how their cooperation is important to helping stabilize the world's recovery from the global financial crisis.

They noted that while there is promising improvement in the pace of growth in China and the United States, they would also work together to support efforts to help countries in Europe with the challenges they face.

Vice Premier Wang Qishan said the second round of strategic and economic talks with officials from the Obama administration was a success and that both sides had in-depth discussions and reached agreements.

Wang says that as the biggest developing country and biggest developed country, the mutual economic relationship of the United States and China is having an impact on the entire world.

The two sides did not make any additional comments regarding requests from Chinese officials for Washington to put an end to curbs on "dual use" high-tech exports that have possible military applications.

The United States is reviewing its export control policy and is expected to announce changes to the policy in the next few months.

China did not make any additional statements regarding its currency policy, which has been a persistent issue. On Monday, Chinese President Hu Jintao stressed China would continue with the gradual reform of its currency, the yuan, but at its own pace.
