Kim Jong-un confirmed his commitment to the "complete denuclearization of Korean Peninsula," in a joint document signed with President Trump in Singapore on Tuesday. According to the press, the text does not mention "complete, verifiable and irreversible denuclearization," however, it does reaffirm the Panmunjom Declaration, signed by Kim on April 27, 2018.
Both countries have agreed to hold follow-up negotiations led by the US Secretary of State Mike Pompeo and a relevant high-level North Korean official, "at the earliest possible date," in order to implement the outcomes of the historic summit.
The AFP News agency also claimed, that the document includes 'security guarantees' for North Korea, however, it is not clear at the moment, what exactly Trump promised Kim in terms of security. Previously, Secretary of State Pompeo declined refused to address possible guarantees, which might include withdrawing the US troops from the Korean Peninsula.
