WASHINGTON - President Barack Obama landed back on US soil early Wednesday after his landmark visit to Myanmar and a three-day tour of Southeast Asia in which he attended a regional summit. The president arrived at Andrews Air Force Base in Maryland, near the US capital, at 12:30 am (5:30 GMT), said a reporter on Air Force One, and then made the short flight back to the White House on his Marine One helicopter. The Asia trip was Obama’s first foreign tour since being re-elected two weeks ago. He met Myanmar’s feted democracy leader Aung San Suu Kyi on Monday, becoming the first serving US president to visit the country formerly known as Burma, and praised its fledgling reform moves after decades of military rule.
