A first step in building a lasting and robust peace regime on the Korean Peninsula as President Donald Trump and North Korea leader Kim Jong Un end their highly anticipated summit with the signing of a document Monday night.

The joint declaration has the U.S. committing to providing security guarantees to North Korea and the country re-affirming a firm and unwavering commitment to complete denuclearization of its part of the world.

"I want to thank Chairman Kim. Spent alot of time together today, a very intensive time. And I would actually say that it worked out for both of us far better than anybody could have expected," President Trump said.
