Myanmar junta supremo Than Shwe smiled briefly but gave nothing away as he listened on Friday to U.N. chief Ban Ki-moon, at the start of what Ban has called a "tough mission" to promote democratic reform, according to Reuters. "I thank you for your invitation. I'm happy to be here and to see you are in good health since I last saw you," Ban told the 76-year-old general, wearing a khaki uniform adorned with medals. The rare meeting with the reclusive general took place in Than Shwe's lavish Bayint Nuang Yeiktha office in Naypyidaw, the new capital hastily built in the hills of Shan Plateau in 2005. Ban, on what he has called a "tough mission" to press the junta to release all political prisoners and hold fair and credible elections, commended the general for his contributions to peace, prosperity and democracy in the former Burma. "I would like to help move your country forward and appreciate your commitment to moving your country forward," Ban said, offering a smile and a firm handshake to the man who has led the military regime for 17 of its 47 years in power. Moments later, the media were ushered out of the room. Ban was expected to ask Than Shwe's permission to meet opposition leader Aung san Suu Kyi, who is on trial for breaching the terms of her house arrest.
