As President Barack Obama arrived in Thailand he was asked whether his visit to Burma tomorrow was premature, given the country's record on human rights.
He said: "This is not an endorsement of the Burmese government. This is an acknowledgement that there is a process under way inside that country that even two years ago nobody foresaw."
US President Barack Obama has spent the day in Thailand at the start of a three-day tour of Southeast Asia.
Barack Obama is touring Southeast Asia to showcase foreign policy achievement and reinforce the U.S. role as a counterweight to China.
