The head of the U.N. nuclear watchdog will meet the North Korean government next month to discuss the shutdown of its nuclear programme and bring the secretive communist state back under U.N. supervision, Reuters reported. International Atomic Energy Agency (IAEA) Director-General Mohamed ElBaradei said he had received an invitation from Pyongyang on Friday, after a deal last week to shut down its Yongbyon nuclear site and allow U.N. inspectors into the country. "The first (issue) of course is how to develop a plan to freeze the Yongbyon facilities, and more importantly to make sure that they come back as a fully-fledged member of the agency," ElBaradei told reporters in Vienna. "I very much welcome this opportunity," said ElBaradei in a joint briefing with U.N. Secretary-General Ban Ki-moon, who is visiting Vienna. A spokeswoman for the IAEA added that ElBaradei planned to go after an IAEA board meeting in March.
