Chinese ministry of trade released the bill imposing economic sanctions on the North Korea on Monday. According to Reuters, the ban will take effect tomorrow, August 15.
The document bans imports of coal, iron ore, lead and seafood from the North Korea.
The sanctions take place due to the recent UN Security Council decision; back then, on August 5, the authority decided that Pyongyang should face restrictions because of systematic missile tests. That might result in North Korea losing about a billion dollars.
