BANDAR SERI BEGAWAN - Myanmar won a new diplomatic prize Thursday for its dramatic political reforms, taking the helm of Southeast Asia's regional bloc despite warnings from some critics that the move was premature.
The one-time international pariah was formally awarded the rotating chair of the Association of Southeast Asian Nations (Asean) for 2014 at the end of the group's summit in the oil-rich sultanate of Brunei.
President Thein Sein said the theme of Myanmar's chairmanship would be "moving forward in unity in a peaceful and prosperous community".
The former general has earned international plaudits and the removal of most Western sanctions for reforms that include freeing hundreds of political prisoners.
Draconian media censorship has been scrapped and opposition leader Aung San Suu Kyi and her National League for Democracy have been welcomed into parliament following landmark by-elections last year.
But the military and its political allies remain firmly in control of the country while religious violence and the continued arrests of activists have tempered optimism about the political changes.
Around 250 people have been killed and more than 140,000 left homeless in several outbreaks of Buddhist-Muslim violence around the country since June 2012.
Addressing the Brunei summit, UN leader Ban Ki-moon said the communal violence remained a concern.
The Asean chairmanship, as well as general elections in 2015, "will be very important milestones for the future of Myanmar," he said.
"It's important that the Asean countries as well as all United Nations member states fully encourage Myanmar authorities so that they can do more on this participatory democratic transition," Ban added.
The 2015 polls will provide a definitive test on whether the military is willing potentially to give up power, with Suu Kyi eyeing the presidency.
Critics said the decision to hand the Asean reins to Myanmar highlighted the bloc's wider disregard for human rights.
"Sadly, respect for human rights has never been an important qualification for being Asean chair," said Phil Robertson, deputy Asia director at New York-based Human Rights Watch.
"Myanmar's human rights record is still highly problematic but this is nothing that Asean ever had a problem with," he told AFP.
"No one should forget that with a few exceptions, Asean continues to be a grouping of frequently dictatorial rights abusing states."
In April, Human Rights Watch accused Myanmar of "a campaign of ethnic cleansing" against members of the Rohingya Muslim minority - an accusation rejected by Thein Sein as a "smear campaign".
Communal unrest last year in the western state of Rakhine left about 200 people dead and up to 140,000 displaced, mainly Rohingyas, who are denied citizenship by Myanmar.
Since violence broke out there last year, thousands of Rohingya - including a growing number of women and children - have fled the conflict in rickety boats, many heading for Malaysia.
For years Myanmar was a source of embarrassment for Asean's more democratic states, overshadowing other problem members such as communist Vietnam and Laos, which have significant human rights issues of their own.
In 2006, Myanmar was forced to renounce the Asean rotating presidency in the face of criticism over its human rights record and the then-ruling junta's failure to shift to democracy.
The Philippines - one of the harshest critics within Asean of the former junta - noted in Brunei that the Myanmar military had relinquished some of its powers.
President Benigno Aquino told Thein Sein that the Philippines would support Myanmar's chairmanship.
Along with the Asean chairmanship, Myanmar will host the East Asia Summit in 2014, which brings Asean members together with the United States, China and Russia, among others.
US Secretary of State John Kerry, speaking to students in Brunei on Wednesday, said Myanmar's reforms were "incomplete", a day after the country released dozens more political prisoners.
Relations between the US and Myanmar - a traditional ally of China - have improved markedly since the end of military rule with US President Barack Obama making a historic visit there last year.
