North Korea has agreed to allow the International Atomic Energy Agency (IAEA) to resume its monitoring of the communist state's nuclear facilities.

Kyodo News Agency quoted sources in the IAEA as saying officials in the North Korean embassy in Vienna, Austria hinted at allowing the U.N. nuclear watchdog to resume inspections of the North's facilities in Yongbyun, depending upon the outcome of the six-party talks.

Kyodo said the IAEA demanded that North Korea also return to nuclear non-proliferation treaty.

Pyongyang had disabled IAEA surveillance devices in the Yongbyon reactor and expelled IAEA inspectors in December, 2002 after the U.S. and its allies cut off heavy fuel oil supplies to the North for violating a 1994 framework agreement to freeze its nuclear activities.
