Although North and South Korea prefer declaring the end of the war first, China advocates a peace treaty which would be legally binding on all parties.

[8] Russian president Vladimir Putin, who reconfirmed the peace treaty with Japan ending World War II, said that North Korea's nuclear issue should be resolved in "a political and diplomatic manner".

Ambassador to the United Nations Kelly Craft announced that the U.S. was ready "to simultaneously take concrete steps" with a flexible approach,[20] for a 'balanced agreement" of the nuclear deal with DPRK.

[25] On August 5, 2017, China's paramount leader Xi Jinping called for Donald Trump to resolve the North Korean nuclear issue through a peaceful resolution based on mutual respect between the nations in the face of heightened military tensions.

[31][32][33] According to a Washington Post analysis, sufficient momentum exists for a declaration ending the Korean War as a useful tool for the Trump administration to speed up North Korea's denuclearization.

Moon is trying to persuade Kim Jong-un to give up his nuclear program and weapons by showing him a brighter economic future with South Korean cooperation.

[47] In Pyongyang during the Arirang Mass Games-2018 Festival, South Korean President Moon Jae-in delivered a seven-minute speech to a crowd of more than 150,000 people, urging the two Koreas to take a giant step toward denuclearization and lasting peace.

[51] Mongolia as a country that transitioned from communism to democracy, it hoped to support a unified Republic of Korea for peace and development in Northeast Asia, and held opinions at the Ulaanbaatar Dialogue (UB) and Mongolian Forum in June 2023.

[52] At the Mongolian Ulaanbaatar Dialogue, the importance of cooperation in Northeast Asia was emphasized in a situation where the number of nuclear-armed countries and tensions between the United States, China, North and South Korea, and China-Taiwan are increasing.

[57] Xi and Moon Jae-in agreed on mutual efforts to bring about a positive change to conditions surrounding the Korean Peninsula after the April 2018 inter-Korean summit.

The president promised to work with Moon to pressure North Korea into abandoning its ICBM and nuclear-weapons programs,[60] which have caused anxiety in the Asia-Pacific region for years.

[65] Three days later, Korean Council for Reconciliation and Cooperation chairman Kim Hong-gul expressed Pyongyang's eagerness to sign a declaration ending the war and its willingness to speed up denuclearization based on mutual trust between the US and North Korea.

Although a comprehensive denuclearization agreement was made during the Trump-Kim summit, a peace treaty would be a crucial condition for North Korea to give up their nuclear arsenal and ICBM program.

[68] On August 4, during the Association of Southeast Asian Nations (ASEAN) Regional Forum 2018, North Korea's nuclear program was the main agenda item.

[72] USFK maintains several nuclear bomber fighters, and North Korea demanded a US safety guarantee in exchange for giving up their nuclear-weapons program.

U.S president Donald Trump met with Kim Jong-un on February 27–28, 2019, in Hanoi, Vietnam, in the second summit meeting between the leaders of the United States and North Korea.

On February 28, 2019, the White House published that the summit was cut short and that no deal was reached, with Trump later elaborating that it was because North Korea wanted an end to all sanctions.

[83] Dr. Chiew-Ping Hoo, a professor at the National University of Malaysia, said that the negotiations at the Hanoi summit changed the minute John Bolton was added at the eleventh-hour to the panel.

[85] Former special assistant to President Ronald Reagan, and a senior fellow at the Cato Institute, Doug Bandow, said that President Trump was unrealistically demanding that Chairman Kim Jong Un dismantle all his nuclear facilities, whereas Chairman Kim was only agreeing to shutting down the YongByon Nuclear facility in exchange for a partial lifting of a few UN sanctions against his country.

[87] According to Abby Bard, a research associate for Asia policy at the Center for American Progress, President Trump's and Chairman Kim's teams need critical space between them to build trust and verify the intentions between the two parties.

[94][95][96][97][98] Some of Senate Republicans including Lindsey Graham praised Mr Trump's pick and mentioned, He's got great negotiating skills, and "he would be a very sound policy adviser.

[101][102][103][104] On December 16, China and Russia proposed that the U.N. Security Council lift a ban on some parts of restrictions including DPRK exporting sea food, textiles and infrastructure projects.

A close U.S. ally, South Korea has also supported the official proposal of easing some sanctions to DPRK, and requested for diplomatic efforts to be focused on resuming nuclear talks.

National security adviser Robert C. O'Brien said "President Trump has shown both with the peace plan and what is right for the American people although it's unpopular, risky, right up until the day of the election."

The US Special Representative to North Korea and the deputy secretary of state, Steve Biegun, have remained engaged in working-level talks with the DPRK.

The foreign ministry adviser of DPRK, Kim Kye Gwan, mentioned that the personal relationship between two leaders is not enough to restart nuclear negotiations.

Chairman Kim declared that the DPRK would abandon its moratorium on nuclear and long-range ballistic missile tests and would soon introduce "a new strategic weapon" based on future "attitude" of the US.
