NEW YORK: United Nations sanctions experts are warning people not to attend a cryptocurrency conference in North Korea in February, flagging it as a likely sanctions violation, according to a confidential report due to be submitted to the U.N. Security Council later this month. The warning comes after the independent U.N. experts told the council in August that North Korea generated an estimated $2 billion for its weapons of mass destruction programs using “widespread and increasingly sophisticated” cyber attacks to steal from banks and crypto currency exchanges. North Korea has been under U.N. sanctions since 2006 over its nuclear and ballistic missile programs. The 15-member Security Council has unanimously strengthened those measures over the years, prompting Pyongyang to look for alternative ways to make money. In April last year, North Korea held its first block chain and crypto currency conference and an organizer told Reuters more than 80 organizations took part. An American who attended has been charged with violating U.S. sanctions. The next conference is due to be held from Feb. 22-29, according to its website. An excerpt from the upcoming annual report by the U.N. sanctions experts, seen by Reuters, warns that presentations at the conference “have included explicit discussions of cryptocurrency for sanctions evasion and money laundering.” It then spells out that U.N. sanctions require countries to prevent the provision of “financial transactions, technical training, advice, services or assistance” if they believe it could be contributing to North Korea’s nuclear or ballistic missile programs or to the evasion of sanctions. The full report is due to be submitted to the U.N. Security Council North Korea sanctions committee later this month. North Korea’s mission to the United Nations did not immediately respond to a request for comment. A British government spokesman and a Security Council diplomat from another country, speaking on condition of anonymity, both said North Korea’s cyber program was used to collect information, evade sanctions and generate revenue. “Supporting the DPRK’s use of cryptocurrency and blockchain technology, risks violating the Security Council’s resolutions because it would unavoidably increase the DPRK’s ability to subvert sanctions and generate revenue for its weapons programs,” the British spokesman said, citing North Korea’s official name, the Democratic People’s Republic of Korea (DPRK). The United States formally charged American digital currency expert Virgil Griffith last week after he attended the North Korean cryptocurrency conference last year. Prosecutors accuse him of providing services to North Korea without U.S. approval and evading U.S. laws.
