Thein Sein spoke to Singapore's Straits Times and said that the military, which controlled policy in Myanmar for half a century, now has no say in government policy. He said, "This is an armed forces that the country has had to rely on for a very long time for security and to meet external threats," according to Reuters.
He added, "So, it is important at this time that they are not left behind entirely. They have a limited role within the constitution. But they are not involved in any way in the direct affairs of government or government policy."
Thein Sein said, "There can't be peace without democracy and there can't be democracy without peace."
