Obama and Biden said the US side attaches great importance to China's stance and views on these issues.

They said the US government sticks to the one-China policy based on the three joint communiques and does not support "Taiwan independence", adding that the United States hopes to see continuous peaceful development of cross-Straight relations.

They also said the United States would like to maintain dialogue with China on human rights and agreed that the two sides should properly handle sensitive issues concerning bilateral ties.

Second, Xi's trip in the United States expanded mutually beneficial practical cooperation in trade and other fields.

During the visit, Xi expounded on the nature of China-US trade ties, saying that they serve as "ballast" and "propeller" of overall bilateral relations.

He used figures and examples to explain how the two economies are complementary to each other and how bilateral trade brings benefits to both sides, making clear the significance of maintaining the steady development of bilateral trade ties.

Xi said China and the United States should resolve their trade frictions through dialogue on equal footing and candid communication, instead of resorting to means of protectionism.

Xi noted the best solution to the trade imbalance between the two countries is to expand US export to China, saying China hopes the US side could soon take concrete steps to ease export restrictions on high-tech products and create a fair business environment for Chinese investors.

In face of the global economic crisis, China and the United States should jointly overcome the hardships and further strengthen macroeconomic policy coordination so as to quicken the development of a comprehensive mutually beneficial economic partnership.

Obama and Biden said they hoped the two nations could solve their trade problems with a practical and constructive attitude and achieve win-win results.
