On January 1, 2024, President Xi Jinping and President of the United States Joe Biden exchanged congratulatory letters on the 45th anniversary of the establishment of diplomatic relations between the two countries.

In his letter, Xi Jinping pointed out that the establishment of diplomatic relations between China and the United States is a major event in the history of bilateral and international relations. Over the past 45 years, despite the ups and downs, the China-U.S. relationship has on the whole moved forward, which has not only enhanced the well-being of the two peoples, but also promoted world peace, stability and prosperity. History has fully proven and will continue to prove that upholding mutual respect, peaceful coexistence and win-win cooperation is the right way for China and the United States to get along with each other as two major countries, and should become the common direction of efforts of both China and the United States in the new era.

Xi Jinping noted that he and President Biden, during their summit meeting in San Francisco, laid out a future-oriented "San Francisco vision", charting the course for the development of China-U.S. relations. The two sides should earnestly implement the important common understandings and outcomes reached between the two heads of state, and take concrete actions to promote the stable, sound and sustainable development of China-U.S. relations.

Xi Jinping emphasized that he is willing to work with President Joe Biden to continue to steer the course of China-U.S. relations, to benefit the two countries and two peoples, and promote the cause of world peace and development.

In his letter, Joe Biden said that since the establishment of diplomatic relations in 1979, the interactions between the United States and China have promoted the prosperity and opportunity in the United States, China, and the world. He said he is committed to managing this important relationship responsibly and looks forward to continuing to advance the U.S.-China relationship based on the progress made by their predecessors as well as the progress they have made at their meetings and discussions on multiple occasions.
