Donald Trump and Kim Jong Un have signed a document in Singapore after the pair reached an historic agreement.
It reaffirms North Korea’s previous commitment to work toward complete denuclearisation of the Korean Peninsula.
The US, meanwhile, has agreed to provide “security guarantees” to North Korea.
It also contains a number of other pledges - including to building "a lasting and stable peace on the Korean Peninsula.”
President Trump claimed that they've taken care of a 'very big and dangerous problem' in the world.
In a press conference after the summit, President Trump hailed the talks as 'honest, direct and productive'.
He said: "Today is the beginning of an arduous process - our eyes are wide open, but peace is always worth the effort, especially in this case.
"Chairman Kim has the chance to seize an incredible future for his people. Anyone can make war, but only the most courageous can make peace."
Trump also suggested the US would stop the 'provocative' war games it holds with South Korea every year - the events having long been a source of tension with the North.
Earlier, the US President and the North Korean leader greeted each other with a 13 second handshake before the first ever face to face meeting between a sitting US President and a North Korean leader.
