DANDONG, North Korea – A North Korean company under UN sanctions for aiding the country’s nuclear and ballistic missiles programs has no presence at the Chinese border city address it registered with local authorities under an alias, NK News has learned.

Millim Technology Company was named by a UN committee last year as the Chinese alias of the Korea Ryonha Machinery Joint Venture Corporation, a machine tools firm blacklisted by the UN Security Council in 2013 for its alleged role in North Korea’s weapons development.
