President Bush has signed a law renewing economic sanctions against Burma for another year.
The measure is a renewal of the Burma Freedom and Democracy Act. It bars imports from Burma, and is intended at pressing Rangoon to improve its human rights record.
Congress passed the legislation after last year's attack on a motorcade carrying Burmese democracy leader Aung San Suu Kyi. She was detained following the incident, and is still under house arrest.
Meanwhile, Assistant U.S. Secretary of State for Democracy, Human Rights, and Labor Lorne Craner says Aung San Suu Kyi's party, the National League for Democracy, remains a viable political force in Burma.
Mr. Craner made the comments to a congressional hearing Wednesday.
