North Korea issued a statement overnight promising it will continue to pursue its nuclear and ballistic missile programs, regardless of new U.N. sanctions passed over the weekend.
North Korea is promising to retaliate a "thousand-fold" against the US in retaliation for new sanctions imposed against the Communist country.
The United Nations sanctions could cut more than a billion dollars in North Korean revenue by banning exports of coal, iron, lead and seafood.
Secretary of State Rex Tillerson opened the door to negotiating directly with Pyongyang, but with conditions.
North Korea responded in a statement saying: "We will pursue our ambitions to maintain supremacy of nuclear power forever by launching intercontinental ballistic missiles. We won't stop for anyone, no matter what they say."
Secretary Tillerson called on China and Russia to enforce the sanctions they voted to approve.
China has increased trade with Pyongyang over the first half of the year, but has cut how much it buys from North Korea, especially coal.
President Trump discussed North Korea during an hour long call this morning with Secretary of State Tillerson and his new Chief of Staff, General John Kelly.
