"Over the past half a century, the China-U.S. relationship has kept moving forward despite twists and turns. It has not only had a profound impact on the two countries, but has also changed the course of history and the world significantly. The world today is going through major changes unseen in a century. As two big countries different in history, culture, social system and development stage, China and the United States are entering a new round of mutual exploration, understanding and adaptation, trying to find a way to get along with each other in the new era. The China-U.S. relationship has once again come to a new critical juncture, facing not only many difficulties and challenges but also great opportunities and potentials. Where this important relationship will be headed is vital for the well-being of the Chinese and American peoples and for the future of the world. The two peoples and the international community hope for a sound, stable and growing relationship between the two countries."
