A draft U.N. Security Council resolution on North Korea calls for blacklisting three key state agencies overseeing Pyongyang's nuclear and missile programs as well as espionage operations, sources said Wednesday.

The agencies -- the General Reconnaissance Bureau, the Ministry of Atomic Energy Industry and the National Aerospace Development Administration -- are among about 30 individuals and entities to be sanctioned by the new resolution, according to the sources.

Also to be blacklisted are North Korean trading and financial firms involved in illicit activities, they said.

The United States and China have put together the draft resolution that is expected to be circulated soon among the other U.N. Security Council members for review. Unless any objection is raised, the council could adopt the resolution as early as Friday.

The General Reconnaissance Bureau, which was established in 2009 from the merger of similar intelligence agencies, has been accused of masterminding a series of provocations, including the

2010 torpedoing of a South Korean warship and the 2014 cyber-attacks on Sony Pictures.

The U.S. State Department imposed sanctions on it in January last year for the hacking attacks, but the agency has not been sanctioned by the Security Council.

The Ministry of Atomic Energy Industry and the National Aerospace Development Administration are in charge of the North's nuclear weapons development and its long-range ballistic missile program, respectively. A U.N. panel of experts has recommended adding them to the sanctions list. (Yonhap)
