The head of the U.N. nuclear watchdog left to North Korea on Tuesday (March 13) on his first trip since the North kicked out inspectors four years ago, saying he hoped for progress on closing its atomic facilities. "We should be able to make some progress on how we can work closer with DPRK after many years of estrangement and also how to see ways and means to implement the six-party agreement," ElBaradei told reporters at his hotel lobby in Beijing. ElBaradei said his trip to North Korea was an important part of the six-party talks' implementing of the initial steps. "I think this obviously initial steps would be important, significant in fact in moving the six-party talks forward." ElBaradei said. North Korea announced in 2005 it had nuclear arms and that it test-detonated its first nuclear device in 2006, drawing U.N. financial and arms sanctions on itself. ElBaradei is seeking to bring North Korea back closer to the IAEA four years after it expelled international nuclear inspectors and quit the global nuclear Non-Proliferation Treaty.
