Vienna  - North Korea has not informed the International Atomic Energy Agency (IAEA) of its plans to restart its nuclear reactor so far, diplomats said Friday.

North Korea agreed to an arrangement last summer under which IAEA inspectors would be stationed permanently at the Yongbyon nuclear complex to monitor that the reactor and other facilities remain shut down.

Foreign ministry official Hyon Hak Bong said earlier on Friday during energy aid talks in the border truce village Panmunjom that Pyongyang was making "thorough preparations" to restore its nuclear facilities, which had been disabled under a multilateral agreement.

The IAEA has installed seals and cameras to monitor the nuclear freeze that North Korea agreed to with the United States, China, Russia, Japan and South Korea, in exchange for energy aid and an easing of sanctions.

North Korea has not requested to remove IAEA seals so far, diplomats said.

Earlier this month, Deutsche Presse-Agentur dpa learned that North Korea had carried out its announcement and started to reverse the process of disabling its nuclear facilities. (dpa)
