S. Korea optimistic on nuclear deal with North

South Korea's point man on North Korea voiced optimism Thursday that agreements reached in a breakthrough deal on curbing North Korea's nuclear weapons program will be implemented. The hardline communist country pledged at the international disarmament talks in Beijing last month to shut down its sole operating nuclear reactor by April 14 in exchange for energy aid and other political concessions. "I believe that the agreements reached under a February 13 deal will be implemented," Unification Minister Lee Jae-joung told reporters at a regular press briefing.
