Leonard Leo, chair of the US Commission on International Religious Freedom, an advisory body, said Vietnam improved its record only when its "feet were held to the fire."

Walter Lohman, director of Asian studies at the conservative Heritage Foundation, said that while the United States had its concerns, Vietnam has at least shown willingness to engage.
