North Korea\'s senior envoy to the six-party talks and vice minister of foreign affairs Ri Yong-ho is expected to meet with South Korean and U.S. officials during his trip to the United States from March 6. Ri is scheduled to attend a seminar hosted by Syracuse University in the U.S. state of New York and make an appearance at a meeting chaired by the National Committee on American Foreign Policy, according to Korea\'s (KBS WORLD) website. The NCAFP meeting is also expected to be attended by Glyn Davies, U.S. Special Representative for North Korea, and Clifford Hart, special envoy for the six-party talks. Officials from both Koreas and the U.S. are expected to negotiate continuously over the denuclearization in North Korea and the resumption of the six-party talks. A diplomatic source in the U.S. said that although an official meeting between the North and South Korean nuclear envoys had not been set, such a meeting could be held in light of Ri\'s experience in high-level talks between the two Koreas.
