The United States, the USSR, France, China, North Korea and South Korea participated in the talks on the conflict in Korea. The peace deal on the Korean Peninsula was formally discussed at the conference by Chinese diplomat Zhou Enlai with US Defense Secretary John Foster Dulles, but no progress was made.  The US deliberately avoided discussing the “Korean Peninsula Peace Treaty,” despite criticism from other representatives at the conference on the negative attitude of the US. The signed ceasefire established the “total cessation of all hostilities in Korea by all armed forces”, which should be imposed by commanders on both sides. However, the ceasefire is only 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 established the Military Demarcation Line (MDL) and the DMZ. The DMZ was agreed as a 2.5-mile-wide (4.0 km) buffer zone between the two Korean nations.  The DMZ follows the Kansas line, where the two sides effectively clashed at the time of the signing of the ceasefire. The DMZ is currently the most defended border in the world as of 2018 [update]. [Citation required] At the 1954 Geneva Conference in Switzerland, Chinese Premier and Foreign Minister Zhou Enlai proposed the implementation of a peace treaty on the Korean Peninsula. However, US Secretary of State John Foster Dulles did not follow this attempt to reach such a treaty.
No final peace agreement has ever been reached.  The signed ceasefire established the Korean Demilitarized Zone (DMZ), the new de facto border between the two nations, established a ceasefire and the final repatriation of prisoners of war.
