FILE - In this undated file photo, Vietnamese-American pro-democracy activist Nguyen Quoc Quan is seen in Ho Chi Minh City, Vietnam. Quan, 59, was arrested at Ho Chi Minh City airport in April soon after arriving on a flight from the United States, where he has lived since fleeing Vietnam by boat as a young man. The detention and looming trial of the democracy activist may be the clearest example of Hanoi's unwillingness to listen to American concerns over human rights. (AP Photo/ Vietnam News Agency, File)
