Korean Peninsula Energy Development Organization

The Korean Peninsula Energy Development Organization (KEDO) was an organization founded on March 15, 1995, by the United States, South Korea, and Japan to implement the 1994 U.S.-North Korea Agreed Framework that froze North Korea's indigenous nuclear power plant development centered at the Yongbyon Nuclear Scientific Research Center, that was suspected of being a step in a nuclear weapons program.
KEDO's principal activity was to construct two light water reactor nuclear power plants in North Korea to replace North Korea's Magnox type reactors. The original target year for completion was 2003.
Since then, other members joined:

1995: Australia, Canada, New Zealand
1996: Argentina, Chile, Indonesia
1997: European Union, Poland
1999: Czech Republic
2000: Uzbekistan
KEDO discussions took place at the level of a U.S. Assistant Secretary of State, South Korea's deputy foreign minister, and the head of the Asian bureau of Japan's Foreign Ministry.
