Democracy icon Aung San Suu Kyi’s opposition announced its return to Myanmar’s political arena Friday, as the country’s nascent reforms received a dramatic seal of approval from the United States. After speaking directly to Nobel laureate Suu Kyi for the first time, in a call from Air Force One, US President Barack Obama said Hillary Clinton would next month become the first secretary of state to visit Myanmar for 50 years. In rare elections a year ago, Myanmar’s military rulers gave way to a nominally civilian administration which released Suu Kyi from years of house arrest and has since made a surprising series of conciliatory gestures.
