Washington (CNN) Vice President Mike Pence said in a wide-ranging speech Friday that President Donald Trump and the United States will continue dialog with North Korea to pressure the country towards denuclearization, after a recent summit between the two countries was cut short due to disagreements in negotiations.

"Last night, Trump returned from a second historic summit with North Korea in Vietnam,'" Pence said at the Conservative Political Action Conference in Maryland, after the US-North Korea summit in Hanoi, Vietnam, broke up earlier than expected without a deal . "The President said it was productive two days and discussions among teams will continue. As President Trump said as he departed, 'Sometimes you have to walk."

Pence continued, saying, "And I can assure you after decades of failure with North Korea, under President Trump's new leadership America will not repeat the mistakes of the past. But for the sake of our security, the sake of the people of the Korean peninsula, President Trump will stand firm until we achieve the complete denuclearization of North Korea."

Pence also praised the President's strides toward denuclearization, remarking that "it's remarkable to think that when I stood at this podium two years ago, North Korea was engaged in regular nuclear tests, launching missiles over Japan, threatening the United States and our allies."

But faced with Trump's pressure campaign on North Korea, Pence said that "the world has witnessed the results. No more nuclear tests. No more missiles being fired."
