North Korea’s flagship operating system developer has registered a branch office in Russia “for market research,” becoming the first DPRK entity to openly set up shop in the country since last year as the two states seek to expand cooperation while flouting global sanctions.

A North Korean company likely affiliated with Red Star Technology Exchange Company opened its representative office under the name “Bulgunbyol Technology Trading Company” in a private house in Vladivostok on Sept. 24, with the help of the DPRK Chamber of Commerce.
