China’s Vice President Xi Jinping is visiting the Oval Office Tuesday in a closely watched diplomatic mission. It's Xi’s first major step onto the international stage, a test run for when he takes over the presidency in March 2013. He's also the first high-ranking Chinese official to visit the U.S. since President Obama announced a military “pivot” toward Asia to counterbalance China's expansion in the region. Further complicating matters, China recently vetoed the United Nations resolution on Syria over the U.S.’s strenuous objections. China announced Tuesday that its envoy held talks with the head of the Arab League. Xi met with Vice President Joe Biden, Secretary of State Hillary Clinton, and Trade Representative Ron Kirk in the White House Tuesday morning before meeting separately with President Obama in the Oval Office.
