The State Department did not provide justification for the finding publicised today. But it comes nearly one year after Kim Jong Nam died at an international airport in Malaysia in an attack authorities said used VX nerve agent.
The determination, made by the department's international security and nonproliferation bureau, carries restrictions on U.S. foreign aid and financial and military assistance that North Korea's heavily sanctioned government is already subject to. It was posted on the website of the Federal Register and takes effect Monday.
According to the Pentagon, North Korea probably has a long-standing chemical weapons program with the capability to produce nerve, blister, blood, and choking agents and likely possesses a chemical weapons stockpile that could be used with artillery and ballistic missiles.
Experts say the Feb. 13, 2017, death of Kim Jong Nam at Kuala Lumpur airport is the only confirmed North Korean use of chemical weapon agents. North Korean defectors have charged that such chemicals have been used against prisoners and disabled people inside the authoritarian nation.
The US and other Western nations have accused Syria of using chemical weapons against rebel-controlled areas of the country, which the government denies.
