BEIJING – China’s President Xi Jinping left Beijing on Tuesday for his first state visit to the United States, with negotiations between the two countries on many key sectors close to a successful outcome.

The state visit - from Tuesday to Friday - would take Xi and first lady Peng Liyuan to Washington and to the US high-tech hub of Seattle, where Xi would reach out to a wide range of US society, including business leaders, students and local officials.

He would also spend three days in New York to attend a series of summits at the UN headquarters marking the 70th anniversary of the founding of the global body. Sources close to the arrangements say the two countries are likely to seal more than 40 agreements and deals, including a major one-on climate change.

The Chinese president would deliver a major policy speech at a dinner for business leaders and other dignitaries on Tuesday night, where many believe he will elaborate on Sino-US ties. Xi and Obama would have a small-scale working dinner in Washington on Thursday night before formal talks on Friday.

"Obama has developed a good personal relationship with Xi, having spent hours with him at Sunnylands (California), and more time with him on his visit to Beijing. So they have a good relationship already," Jeffery Bader - former special assistant to the US president for national security affairs – said.

"I think it is important for the two presidents to make statements on their joint commitments to managing the economic relationship, jointly dealing with global economic turbulence, and working to stabilise and send a reassuring message to markets in both countries," he added.
