The United States says its top nuclear envoy will focus discussions on North Korea’s nuclear declaration when he visits Pyongyang next week.

State Department spokesman Sean McCormack told reporters Wednesday that Christopher Hill will visit Pyongyang on Monday and underline the importance of the North declaring all of its nuclear programs and materials by the end of the year as promised under an October 3rd six-way nuclear agreement.

He said Hill will make it clear to North Korean officials that all aspects of the North’s nuclear program should be in the declaration.

Meanwhile, Hill confirmed to reporters in Japan that he will be visiting Pyongyang from Monday to Wednesday. He added that he will travel to the Yongbyon nuclear complex to review progress made regarding the North’s nuclear disablement and will later meet with his North Korean counterpart Kim Kye-kwan.

He said the U.S. is trying to review the second phase of the North’s nuclear dismantlement process to make sure that everything is done by year's end as planned. He said he also hopes to hold discussions about what the next phase might look like.

Hill added that he expects Pyongyang to give the first draft of its nuclear declaration to the U.S.-led nuclear disablement team that is currently in Yongbyon.
