The House on Monday passed a bill by voice vote to enhance U.S. sanctions against North Korea for its nuclear proliferation program.

The measure would prevent sanctioned North Korean officials from entering the U.S. or its financial system. It would also block any assets with connections to North Korea's proliferation activities or human rights violations.

"By shutting down North Korea’s illicit activities, we deprive the Kim regime of the money he needs to pay his generals and to conduct nuclear weapons research," said House Foreign Affairs Committee Chairman Ed RoyceEdward (Ed) Randall RoyceFacebook is complicit, not a victim, in the abuse and misuse of personal data Trump rolls the dice on North Korea Tom Steyer announces M effort to bring out young voters in Florida, California MORE (R-Calif.). 

"North Korea is undoubtedly one of the most significant security threats that we here face and our allies face," Royce added.
