US President Barack Obama walks to his car upon his arrival on Air Force One at Paya Lebar Air Base in Singapore on November 14, 2009, the venue of the Asia-Pacific Economic Cooperation (APEC) summit. Leaders of the 21-member Asia-Pacific Economic Cooperation (APEC) forum representing more than half the global economy opened annual talks. At meetings heading into the two-day summit, leaders including Chinese President Hu Jintao warned that resurgent trade protectionism risked choking off a nascent recovery after the world's worst financial crisis in decades. The APEC heads of government, who lead a total of 2.6 billion people stretching from the United States to impoverished Papua New Guinea, were expected to call on their officials to explore a Pacific-wide free trade area.
