China's Vice President Xi Jinping begins a four-day visit to the United States Monday amid major challenges in relations between the two countries.
White House officials say the visit by the man expected to become China's Communist Party chief later this year and the country's president in 2013 will cover a wide range of political, economic, security and human rights issues.
On Tuesday, Xi Jinping will begin a day of meetings, including two hours of discussions with his formal host, U.S. Vice President Joe Biden and an Oval Office talk with President Barack Obama.
