Officials say Chinese Vice President Xi Jinping arrived under tight security in Burma Saturday for an official overnight visit as part of a four-nation tour.

The officials said Xi will meet top leaders, including head of the military government Senior General Than Shwe, before he departs Sunday for Cambodia. 

The officials said the two are expected to sign several agreements during the visits, although they could provide no details.

While in the main city of Rangoon, Xi is scheduled to visit a gem emporium and the sacred Shwe Dagon pagoda, before flying to the administrative capital of Naypyidaw Saturday evening.

Xi's Asian tour has already taken him to Japan and South Korea.  Cambodia will be his last stop.
