Russia’s report said that the number of North Korean workers with valid work permits decreased from 30,023 to 11,490 persons.
In its report, China, the strongest ally of North Korea, said more of half of its income-earning North Korean nationals had been repatriated.
A UN diplomat confirmed to CNN that one-page reports from Beijing and Moscow were sent to the committee on sanctions, as required by a December 2017 Council resolution demanding repatriation of all North Korean workers by the end of this year.
China’s report also noted that it does not wish for the submission to be made public.
The US has pushed in recent years for sanctions on North Korea to be strengthened.
The United States believes that North Korea has some 100,000 workers abroad, with the majority in China and Russia. North Korean workers overseas are seen as a source of funding for the country’s nuclear and missile program, so repatriating them cuts off a vital lifeline for the regime.
North Korea has long sought the removal of UN sanctions which have put a stranglehold on their economy, portraying them as a violations of sovereignty.
