WASHINGTON (Reuters) - The United States on Tuesday imposed sanctions on 13 Chinese and North Korean organizations Washington accused of helping evade nuclear restrictions against Pyongyang and supporting the country through trade of commodities like coal.

The U.S. Treasury announced the action one day after President Donald Trump put North Korea back on a list of state sponsors of terrorism, on its website.
