North Korea has faced several rounds of sanctions over its nuclear and ballistic missile tests, conducted in violation of the UNSC resolutions. In response to these activities, in August the UNSC imposed sanctions on Pyongyang, targeting exports of coal, iron ore, and seafood from the Asian nation to UN member states.
In December, new sanctions against North Korea were imposed, strengthening the measures regarding the supply, sale or transfer of all refined petroleum products, including diesel and kerosene to North Korea.
