NEW YORK, Sept. 28  -- Chinese President Xi Jinping left here for Beijing on Monday after concluding his first state visit to the United States and first appearance at the UN headquarters.

On Sept. 22, Xi arrived in the U.S. West Coast hub of Seattle, where he attended a China-U.S. governors forum and delivered a speech on China-U.S. relations at a welcoming dinner hosted by local governments and friendly organizations.

Calling for concerted efforts to advance the new model of major-country relationship between China and the United States, he suggested in the speech that the two countries read each other's strategic intentions correctly, firmly promote win-win cooperation, manage differences properly and effectively, and foster friendly feelings between the two peoples.

He also reached out to a cross-section of American society, talking with entrepreneurs of both countries and visiting a Boeing factory, the Microsoft headquarters and a local high school.

Xi's state visit to the United States culminated in the capital city of Washington. Upon his arrival in the city on Sept. 24, he had a three-hour-long informal meeting with his U.S. counterpart, Barack Obama.

Welcomed with the full pomp and circumstance of a state arrival ceremony at the South Lawn of the White House, including a 21-gun salute, Xi held formal talks with Obama, met the press and attended a state dinner on Sept. 25.

When addressing the welcoming ceremony, Xi said China and the United States "have no choice but to seek win-win cooperation."

The Chinese president made a six-point proposal for the development of China-U.S. relations during talks with Obama, which he described as "fruitful and constructive" when meeting the press.

He also met U.S. Congress leaders and attended a welcoming luncheon hosted by Vice President Joe Biden and Secretary of State John Kerry.

Xi's visit yielded fruitful results, with a China-U.S. joint presidential statement on climate change released alongside a 49-item outcome list.

Concluding his state visit to the United States, Xi arrived in New York in the early morning of Sept. 26 for a series of UN summits and conferences upon the 70th anniversary of the establishment of the world body.

Xi addressed the UN General Assembly, the UN Sustainable Development Summit, a women's affairs summit and a peacekeeping summit; presided over a South-South cooperation roundtable co-organized by China and the United Nations; and attended a leader's luncheon on climate change.

At those gatherings, Xi expounded China's stances on international affairs, called for a new type of international relations and announced a series of measures in support of the UN and developing countries.

During his stay in New York, he also met with UN Secretary General Ban Ki-moon, Romanian President Klaus Iohannis, Bangladeshi Prime Minister Sheikh Hasina, Sierra Leone President Ernest Bai Koroma, Nigerian President Muhammadu Buhari, Iranian President Hassan Rouhani, Danish Prime Minister Lars Loekke Rasmussen and Greek Prime Minister Alexis Tsipras.
