The Sunshine Policy instituted by South Korean president Kim Dae-jung in 1998 was a watershed in inter-Korean relations. It encouraged other countries to engage with the North, which allowed Pyongyang to normalize relations with a number of European Union states and contributed to the establishment of joint North-South economic projects. The culmination of the Sunshine Policy was the 2000 Inter-Korean summit, when Kim Dae-jung visited Kim Jong-il in Pyongyang. Both North and South Korea signed the June 15th North–South Joint Declaration, in which both sides promised to seek peaceful reunification. On 4 October 2007, South Korean president Roh Moo-hyun and Kim Jong-il signed an eight-point peace agreement.
