Jeong Eun-bo, South Korea's head negotiator in the defense cost-sharing talks, met with U.S. officials for two days in Washington this week. By the end of his trip, the two countries had not reached any conclusions, he said. "At this point, we are in a situation where we need to continue to narrow our differences. It is not that we have reached a concrete result," Yonhap reported that Jeong said at Dulles International Airport on Dec. 6. .
