In order to address world economic imbalances, countries around the world should make joint efforts to adjust their economic structure.

Since the beginning of the 21st century, thanks to the concerted efforts of both sides, China-U.S. relationship has on the whole enjoyed steady growth. Since President Obama took office, we have maintained close contact through exchange of visits, meetings, telephone conversations and letters.

China has adopted and is implementing its national climate change program. This includes mandatory national targets for reducing energy intensity and discharge of major pollutants and increasing forest coverage and the share of renewable energy for the period of 2005 through 2010.

The world economy today is recovering slowly, and there are still some destabilising factors and uncertainties. The underlying impact of the international financial crisis is far from over.

The Chinese culture belongs not only to the Chinese but also to the whole world.

Only reform and opening up can develop China. We must not be afraid of any risks, and not be confused by any distractions.

In the past 20 years and more since China embarked on the road of reform and opening up, we have moved steadfastly to promote political restructuring and vigorously build democratic politics under socialism.
