Shortly after his arrival in Washington DC, Xi went to the White House at the invitation of Obama.

The leaders then talked as they walked together to Blair House along Pennsylvania Avenue. Obama extended a warm welcome to Xi on his state visit to the US.

Xi said he was glad to visit, and his stop in Seattle was a pleasant journey that bore fruit.

"I expect to, through the state affairs activity in Washington DC, embark on in-depth exchange of views with you upon the bilateral relationship and issues of common concern, in order to reach more consensus and have more outcomes," Xi said.

US senior officials attending the meeting included US Vice-President Joe Biden and US Secretary of State John Kerry.

Xi noted that he and Obama agreed upon building a new type of relationship between major countries during their meeting in Annenburg, California, in June, 2013, and they had a long discussion at Yingtai in Beijing last November during Obama's state visit to China.

"Such in-depth communication is helpful to outlining directions for China-US relationship development and to injecting momentum into it," Xi said.
