FILE - In this Nov. 19, 2012 file photo, U.S. President Barack Obama waves to the media as he embraces Myanmar opposition leader Aung San Suu Kyi after they spoke to the media at her residence in Yangon, Myanmar, Monday. The United States is unwinding two decades of sanctions against Myanmar, as the country's reformist leadership oversees rapid-fire economic and political change. Obama's visit this week, the first by a serving U.S. president, is a sign of how far relations have come. But Washington continues to take a calibrated approach to easing sanctions, keen to retain leverage should Myanmar's reform momentum stall. (AP Photo/Khin Maung Win, Pool, File) less
