South Korea’s Foreign Minister Ban Ki Moon is in Washington for discussions with U.S. officials on North Korea’s nuclear program. Both countries are represented in six-nation talks on the North Korean nuclear crisis. The talks are set to resume in Belling at the end of this month.
     Speaking on CNN’s "Late Edition," South Korean Foreign Minister Ban Ki-Moon sounded upbeat about the current round of six party talks on North Korea’s nuclear program.
     "I think during the last round of our six party talks, we have entered into a stage of real and substantive negotiations," he said. "This is what we have been doing and, with close consultations between Korea and the United States, also with other related parties, I think we are more or less optimistic that we will be able to result in a substantive resolution of nuclear weapons program this time."
     The talks also include North Korea, China, Japan and Russia.
