SINGAPORE, North Korean leader Kim Jong-un has reaffirmed his commitment to the "complete denuclearization of the Korean Peninsula" in a written agreement with U.S. President Donald Trump on Tuesday.

The four-point joint statement fell short of codifying the U.S. demand for "complete, verifiable and irreversible" dismantlement. It also did not specify a timeline or how to proceed with the denuclearization process, which Trump said earlier would start "very, very quickly."

The joint text was issued after the leaders' unprecedented summit at the Capella Hotel on the Singaporean resort island of Sentosa. Following the summit, Trump called their agreement "comprehensive" and said that he had developed a "very special bond" with Kim.

In the agreement, the two sides also committed to establishing "new" bilateral relations and making joint efforts to build a "lasting and stable" peace regime on the peninsula.

In addition, they agreed to recover the remains of prisoners of war and those missing in action during the 1950-53 Korean War, including the immediate repatriation of those already identified.

"President Trump and Chairman Kim Jong-un conducted a comprehensive, in-depth and sincere exchange of opinions on the issues related to the establishment of a new US-DPRK relations and the building of a lasting and robust peace regime on the Korean Peninsula," the joint statement said.

DPRK stands for the North's official name, the Democratic People's Republic of Korea.

"President Trump committed to provide security guarantees to the DPRK, and Chairman Kim Jong Un reaffirmed his firm and unwavering commitment to complete denuclearization of the Korean peninsula," it said.

Though it marked a milestone in the checkered history of the U.S.-North Korea relations, the agreement is expected to draw criticism from those who wanted to see specifics of the denuclearization process.

Both U.S. and South Korean officials have anticipated that the summit will mark the "start" of a denuclearization process in an indication that it may take time.

Trump and Kim arrived in the Southeast Asian country on Sunday. They are set to leave later on Tuesday.
