Inter-Korean summits are meetings between the leaders of North and South Korea. To date, there have been five such meetings so far (2000, 2007, April 2018, May 2018, and September 2018), three of them being in Pyongyang, with another two in Panmunjom. The importance of these summits lies in the lack of formal communication between North and South Korea, which makes discussing political and economic issues difficult. The summits' agendas have included topics such as the ending of the 1950-53 war (currently there is an in force), the massive deployment of troops at the DMZ (approximately two million in total), the development of nuclear weapons by North Korea, and human rights issues.
