The US, South Korea and Japan urged UN member states on Friday to ban North Korea from sending workers overseas, claiming they help fund Pyongyang's nuclear program.

The appeal came after the top envoys of the three countries met in Seoul to discuss measures to control North Korea's growing nuclear arsenal.

"Overseas DPRK IT workers continue using forged identities and nationalities to evade UNSC sanctions and earn income abroad that funds the DPRK's unlawful weapon of mass destruction and ballistic missile programs," the three officials said in a joint statement, using the acronym for North Korea's official name.

The representatives of Japan, South Korea and the US also alleged that North Korea is involved in "malicious cyber activities" that help expand its military.

"We are also deeply concerned about how the DPRK supports these programs by stealing and laundering funds as well as gathering information through malicious cyber activities," the joint statement said.

Envoys urge follow-through on UN resolution

Under a 2017 UN resolution, member states had agreed for a December 2019 deadline to send back all North Koreans working abroad.

The envoys called on the international community to abide by the UN resolution on banning North Korean workers.

In December, South Korea's intelligence agency said that in the last five years, North Korean hackers had stolen cryptocurrency and virtual assets worth 1.5 trillion won ($1.2 billion; €1.04 billion).

Sung Kim, the US special representative to North Korea, said that with its nuclear and missile programs and "malicious cyber program" Pyongyang threatens global security.

The trilateral meeting is likely to anger North Korea, which had earlier warned it was the three countries' efforts for security cooperation that led Pyongyang to boost its own military power.
