The US imposed on Thursday sanctions against a Turkish-based company, its top directors, and a North Korean diplomat, accusing them of trading in weapons and luxury goods with Pyongyang in violation of international sanctions, Reuters reported.

The U.S. Treasury said in a statement that SIA Falcon International Group, which also has a branch in Latvia, would be blacklisted for exporting weapons into or from North Korea.

It also listed SIA Falcon Chief Executive Huseyin Sahin and its general manager, Erhan Culha, for having “acted or purported to act for or on behalf of, directly or indirectly SIA Falcon.”

Additionally, the U.S. Treasury imposed sanctions on Ri Song Un, the economic and commercial counselor at North Korea’s embassy in Mongolia. It said SIA Falcon officials hosted Ri earlier this year in Turkey to negotiate weapons deals with him.
