The U.S. issued sanctions against 8 North Korean banks Tuesday, ramping up the pressure on Kim Jong-un's regime to roll back its nuclear program, per CNN. The Trump administration also slapped sanctions on more than two dozen people linked to North Korea's financial network, operating in China, Russia, Libya, and the UAE.

Treasury Secretary Steven Mnuchin said, "This further advances our strategy to fully isolate North Korea in order to achieve our broader objectives of a peaceful and denuclearized Korean peninsula."
