NAYPYITAW/YANGON (Reuters) - Members of Aung San Suu Kyi's victorious National League for Democracy (NLD) were in tears on Wednesday as Myanmar swore in its first president with no military ties in more than half a century.
Htin Kyaw, a close friend and confidant of the Nobel peace prize laureate, was hand-picked by her to run Myanmar's government because a constitution drafted by the former junta bars the democracy champion from the top office.
In a short address to the chamber, Htin Kyaw reiterated Suu Kyi's stance on the importance of changing the 2008 charter, which entrenches the military's powerful position in politics, and called for national reconciliation.
NLD lawmakers were emotional at the scale of the achievement after decades of struggle, including years when many of them were jailed or, like Suu Kyi herself, put under house arrest.
"I couldn't sleep last night. Our president U Htin Kyaw's speech is something we have never heard before in the country," NLD lawmaker Thiri Yadana, 28, said.
"He promised that he will work for the country with the respect to our leader Aung San Suu Kyi. It's such a big step and this has happened because everybody pushed together forward."
Relations between the armed forces and Suu Kyi will define the success of Myanmar's most significant break from military rule since the army seized power in 1962.
"Our new government will implement national reconciliation, peace in the country, emergence of a constitution that will pave the way to a democratic union, and enhance the living standard of the people," said Htin Kyaw, sporting the NLD's traditional burnt orange jacket.
"We have the duty to work for the emergence of a constitution that is appropriate for our country and also in accordance with democratic standards."
Tension had simmered in the run-up to the November election and as the NLD prepared to take power. Suu Kyi wants to demilitarize Myanmar's politics but effectively needs the support of the military to do so.
The armed forces are guaranteed three ministries and control a quarter of parliamentary seats - enough to give them a veto over constitutional amendments and potentially limit the scope of Suu Kyi's reforms.
Suu Kyi is poised to steer the government from within, acting as a super-minister overseeing education, foreign affairs, electric power and energy - and the president's office.
Before Htin Kyaw addressed the parliament, he and two newly elected vice presidents held the junta-drafted constitution in their hands and took the oath simultaneously, repeating after the parliament speaker Mahn Win Khaing Than:
"I will always be loyal to the Union of Myanmar and will always put non-disintegration of the union, national unity and perpetuation of sovereignty at the forefront," read the first line of the oath.
Myanmar army chief Min Aung Hlaing attended the ceremony.
Htin Kyaw, elected by the NLD-dominated parliament this month, runs a charity founded by Suu Kyi and has been a trusted member of her inner circle since the mid-1990s. He is not a lawmaker.
Hundreds of diplomats and representatives of non-governmental organizations attended the ceremony. Events at the presidential palace and an official dinner were planned to celebrate the occasion.
President Barack Obama, who has visited Myanmar twice and hopes to make its transition to democracy a foreign policy legacy of his presidency, praised Htin Kyaw and the peaceful transfer of power.
"The United States looks forward to being a friend and partner," even as the country faces economic and other challenges going forward, he said in a statement.
