The U.S. State Department has apparently expressed concerned that UN member states may lack the ability to fully implement the sanctions on North Korea.
This is according to report obtained by the American publication Foreign Policy.
The report, submitted to Congress in April, says one of the most significant challenges to the North Korea sanctions is a lack of international capacity.
The State Department said it's offering training to countries and private companies to help them identify and stop the money laundering and commercial activities believed to help Pyeongyang get funding.
The U.S., it said, is urging allies to put more sanctions on North Korean entities because the sanctions so far have not prevented the North from accelerating its nuclear and missile programs.
