The United States has once again ranked North Korea as having the poorest record in preventing human trafficking.
In its 2011 Trafficking in Persons Report released on Monday, the U.S. State Department assessed efforts by 184 governments to fight sexual exploitation, forced labor and modern-day slavery.
Washington identified 23 nations as failing to meet minimum international standards including North Korea, the Democratic Republic of Congo, Saudi Arabia, and Iran. North Korea has been on the list every year since 2003.
Meanwhile, South Korea was grouped with the first tier, which lists countries that fully comply with the U.S.' minimum standards.
