Asian leaders Tuesday called for Western sanctions against Myanmar to be lifted after its historic polls, as they held summit talks also dominated by North Korea and maritime disputes with China. The call came amid international praise for Myanmar's by-elections on Sunday which gave democracy leader Aung San Suu Kyi, a Nobel laureate and former political prisoner, a seat in parliament for the first time. Leaders of the Association of Southeast Asian Nations (ASEAN) “call for the lifting of all sanctions on Myanmar”, Cambodian Secretary of State Kao Kim Hourn told reporters on the sidelines of the bloc's summit in Phnom Penh. “The lifting of sanctions would contribute positively to the democratic process and especially economic development of Myanmar,” he said, quoting leaders inside the meeting room. Election monitors from Cambodia, which holds ASEAN's chair in 2012, have already declared the polls free and fair, and said sanctions imposed over the Myanmar military's long record of rights abuses should be lifted. ASEAN secretary-general Surin Pitsuwan on Monday said the vote should contribute to the “reintegration of Myanmar into the global community”. The by-elections are the latest sign that Myanmar's military is genuine about loosening its grip on power after four decades of brutal rule which made the country a diplomatic pariah and economic backwater. Over the past 12 months the country's quasi-civilian government, led by ex-general Thein Sein, has freed hundreds of political prisoners, eased media restrictions and welcomed the opposition back into politics. At the last ASEAN summit in November, Myanmar was rewarded for its reforms by being promised the bloc's chairmanship in 2014. It is also eager to win greater foreign investment with the prospect of sanctions being lifted. The easing of most US sanctions would require approval in Congress, where lawmakers have welcomed changes in Myanmar but also urged caution as they seek progress on more fronts including resolving ethnic violence. The 27-nation EU already lifted some sanctions on the regime this year to encourage reforms and foreign ministers will decide the next steps when they meet on April 23 in Luxembourg. ASEAN comprises Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand and Vietnam – a grouping of nearly 600 million people from disparate economic and political systems.
