U.S. impose sanctions on Chinese companies for aiding N. Korea

The United States imposed sanctions on two Chinese shipping companies it says helped North Korea evade sanctions issued by Washington over its nuclear program, according to the U.S. Treasury Department website.

The U.S. government also issued an updated advisory listing 67 vessels that have engaged in illicit transfers of refined petroleum with North Korean tankers or were believed to have exported North Korean coal, according to a statement.
