South Korea’s nuclear envoy Wi Sung-lac visits Washington Wednesday to discuss North Korea’s latest efforts to revive long-stalled talks on its nuclear programs.

Wi told South Korea’s Yonhap news agency before his departure that he intends to coordinate opinions on how to move forward on talks with North Korea. He said he wants to talk about how to follow up recent discussions between the two Koreas and between North Korea and the United States.

In Washington, State Department spokeswoman Victoria Nuland said Tuesday that this week’s talks are designed to make sure Washington and Seoul are agreed on how to approach the North Korea issue. But she said Pyongyang must do more if it wants to see the six-nation negotiating process resume.

The United States, Russia, China, Japan and South Korea have been negotiating with North Korea for eight years to get it to give up its nuclear weapons programs in exchange for food, energy and aid. The talks have been frozen since Pyongyang quit the negotiations in 2008, and later resumed testing of nuclear weapons and ballistic missiles.

North Korea has been seeking a resumption of the talks in recent months but South Korea and the United States have insisted that it first follow through on past promises to disarm.

During talks with Russian President Dmitry Medvedev last month, North Korean leader Kim Jong Il expressed a willingness to impose a moratorium on his country’s nuclear program if the talks resume.

In July, nuclear envoys from the rival Koreas held rare talks on the sidelines of the ASEAN security conference in Bali, Indonesia. That was followed by a round of talks between North Korean and U.S. diplomats in New York.

Nuland said Wi will meet this week with Deputy Secretary of State William Burns, Assistant Secretary of State for East Asia-Pacific Kurt Campbell, special representative for North Korea Stephen Bosworth, and special advisor for non-proliferation and arms control Robert Einhorn.
