On July 19, 1953, delegates reached agreement on all members of the agenda.  July 27, 1953 at 10 a.m.m. The ceasefire was signed by Nam IL, delegate of the KPA and the VPA, and William K. Harrison Jr., UNC delegate.  Twelve hours after the signing of the document, all the rules approved by the ceasefire began.  The agreement provided for oversight by an international commission. The Neutral Nations Monitoring Commission (NNSC) was set up to prevent reinforcements from being brought to Korea, either additional military personnel or new weapons, and inspection teams of NNSC members from Czechoslovakia, Poland, Sweden and Switzerland are deployed throughout Korea.  A telegram from Rochkin to Beijing to Moscow informing Soviet leaders of the conditions under which the Chinese will consider a ceasefire on the Korean peninsula. Report by Ridgway, commander-in-chief of UN forces in Korea on meetings between the UN command and North Korea to negotiate a ceasefire in Korea.
The ceasefire has always been designed as a temporary measure. In March 2013, North Korea announced the abolition of all non-aggression pacts with South Korea. It also closed the border and the direct telephone line between the two Koreas.  North Korea also stated that it had the right to conduct a pre-emptive nuclear attack.  A UN spokesman said that the ceasefire agreement had been adopted by the UN General Assembly and could not be unilaterally dissolved by either North Korea or South Korea.  On March 28, 2013, the United States sent two stealth B-2 Spirit bombers to South Korea to participate in ongoing military exercises in the region, including dropping ammunition on a South Korean bombing room. It was the first non-stop B-2 tour from the United States to Korea.  Following this mission, North Korean media announced that they were preparing missiles ready to attack U.S. targets.  In May 2013, North Korea proposed to open negotiations for a peace treaty to replace the ceasefire agreement.   The signed ceasefire established a « complete cessation of all hostilities in Korea by all armed men » which should be imposed by the commanders of both sides.
However, the ceasefire is merely a ceasefire between the armed forces and not an agreement between governments to normalize relations.  No formal peace treaty has been signed and normalized relations have not been restored. The ceasefire founded the Military Dearcation Line (MDL) and the DMZ. The DMZ was agreed as a 4.0 km wide buffer zone between the two Korean nations.  The DMZ follows the Kansas Line, where the two sides clashed at the time of the signing of the ceasefire. The DMZ is currently the most defended national border in the world from 2018. [Citation required] In 2013, North Korea argued that the ceasefire was a transitional measure and that North Korea had made a series of proposals to replace the ceasefire with a peace treaty, but the United States did not react seriously. In addition, the Military Arms Control Commission and the NNSC have been effectively dismantled for a long time, which has paralyzed the ceasefire monitoring functions. North Korea believes that the annual U.S. and South Korean exercises provoke Key Resolve and Foal Eagle and threaten North Korea with nuclear weapons.  JoongAng Ilbo reported that U.S. nuclear-weapon ships participated in the exercise and that the Pentagon publicly announced that the B-52 bombers that had flown over South Korea confirmed the U.S.
« nuclear umbrella » for South Korea.  At the Geneva Conference in Switzerland in 1954, Chinese Prime Minister and Foreign Minister Zhou Enlai proposed the implementation of a peace treaty on the Korean peninsula.
