North Korea

If Trump keeps his promise to do away with the Iran deal, it won't be the first time a Republican administration drops an arms deal inked by Democrats. Something similar happened under George W. Bush.

The U.S. Department of the Treasury says a Chinese conglomerate on the North Korean border has helped blacklisted North Korean companies procure raw materials that could be used for nuclear weapons.

North Korea may face tougher sanctions in response to its most recent nuclear test, the most powerful blast yet. But Pyongyang keeps finding workarounds to the punitive measures.
