The holdup was a result of an EU ban on its factories exporting chemicals used in lethal injections. The ban was issued because the EU regards capital punishment as a human rights violation. It has left Vietnam unable to execute a prisoner since November 2011, when the country decided to switch from firing squads to lethal injections on humanitarian grounds.
Vietnam's old law governing executions stipulated the names of the three chemicals produced in the EU that had to be used in lethal injection. The new law issued this week doesn't mention the chemicals by name, meaning local versions can be produced and used. The law will take effect on June 27.
Vietnam, a one-party state that routinely sentences government critics to long prison terms, is under considerable international pressure to improve its human rights record, which most observers say has gotten worse over the last two years.
Jessen suggested that stopping executions would have earned Vietnam praise among the international community. "A moratorium would have been a positive sign at a time when we need positive signs," he said.
