US Vice President Joe Biden (R) meets with Chinese Vice President Xi Jinping in the Roosevelt Room at the White House in Washington, DC, February 14, 2012. Xi, who arrived in Washington on Monday, is expected to succeed President Hu Jintao in 2013. Chinese presidents generally serve two five-year terms, meaning Xi could be in charge when some experts forecast that China will surpass the United States as the world's largest economy.
