The agreement said the two countries would co-operate towards "new relations" while the US would provide "security guarantees" to North Korea.
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.
