US President Donald Trump says his talks with North Korean leader Kim Jong-un that ended in a joint agreement were "honest, direct and productive".
Mr Trump said he would halt "war games" while Mr Kim had promised to destroy a missile testing site.
Their agreement also included a commitment from Mr Kim to rid the Korean peninsula of nuclear weapons.
It is the first time a sitting US president and North Korean leader have met.
The pair shook hands, held talks together and ate lunch accompanied by advisers.
It caps a remarkable turnaround for the two, who only last year were engaged in angry threats.
What did they agree?
The summit centred on nuclear disarmament and reducing tensions.
The agreement said the two countries would co-operate towards "new relations" while the US would provide "security guarantees" to North Korea.
On nuclear weapons, Mr Kim "reaffirmed his firm and unwavering commitment to complete denuclearisation of the Korean peninsula".
Announcing the agreement to reporters, Mr Trump said that Mr Kim had agreed to "verified" denuclearisation - a key US demand before the summit.
Mr Trump also said that he had raised the issue of human rights with Mr Kim, who runs a totalitarian regime with extreme censorship and forced-labour camps.
