A Japanese newspaper has revealed Japan and the United States are considering constructing an underground nuclear waste storage complex in the Asian country of Mongolia. According to the report, Japan and the United States hope to promote nuclear power overseas, promising new contractors that nuclear waste could be disposed at the complex. U.S. and Japanese officials have confirmed they have held discussions with Mongolia about nuclear waste management, but denied aspects of the report. The United States and Mongolia signed a memorandum of understanding on nuclear power in September 2010.
