In September, Moon and Kim exchanged friendly letters about COVID-19 and the typhoons that hit Korea.  On 22 September, Moon addressed the UN General Assembly and called for a “permanent peace regime” in Korea. Kelly Craft, the U.S. ambassador to the United Nations, backed his request and said that considerable progress had been made so far in the negotiations.  On the same day, the crew of a North Korean patrol vessel killed a South Korean fishing officer they met off their coast and detonated his floating craft. Kim apologized to South Korea for the incident.  In November, at an ASEAN security meeting, the South Korean Ministry of Defence reaffirmed its commitment to the peace process.  The Korean Peninsula Peace Treaty is a proposal to formally end military hostilities on the Korean Peninsula following the 1953 Korean ceasefire agreement implemented by the United Nations after the Korean War. At the inter-Korean summit on 27 April 2018, Kim Jong-un and Moon Jae-in signed the Panmunjom Declaration; The declaration included an agreement on reciprocal efforts and points of action to transform the ceasefire agreement into a peace treaty with the cooperation of the United States and China.   At the 2018 Trump-Kim Summit, U.S. President Donald Trump and Kim signed a joint statement reaffirming Panmunjom`s declaration.
 From Liberia to Northern Ireland, women have played an important role in peace agreements. In August, Secretary of State Kang said she had held “substantial” consultations on a formal end to the Korean War with the Chinese and U.S. foreign ministers.  Chinese Foreign Minister Wang Yi called for a statement.  North Korean Foreign Minister Ri Yong Ho said he was “alarmed” by the U.S. insistence on maintaining sanctions until North Korea was denuclearized, and what he said was the reluctance of the United States to declare the end of the Korean War.  According to Vox, Trump had reached an agreement with North Korea to sign a declaration to end the Korean War, both at a meeting at the White House on June 1. and during the Singapore Summit. However, National Security Adviser John Bolton and Defense Secretary Jim Mattis refused to sign the declaration before denuclearization.  Denuclearization talks between the Democratic People`s Republic of Korea (DPRK) and the United States have stalled since the second summit between SUPREME DPRK leader Kim Jong Un and U.S. President Donald Trump in February 2019 in the Vietnamese capital Hanoi.
However, the Trump administration insists Kim must first reduce his nuclear arsenal by 60-70% – or make another major concession – before the United States signs a peace declaration. The agreements fall into three categories: military, economic and societal. According to Gallucci, the framework agreed in 1994 set a precedent for solving North Korea`s nuclear and military problems.   David C. Kang, director of the University of Southern California Korean Studies Institute and professor of international relations, reviewed efforts to date to resolve nuclear problems based on years of negotiations between the United States and North Korea.
