SEOUL, Oct. 17 (Yonhap) -- The office of President Moon Jae-in said Wednesday that South Korea is working closely with the United States as it seeks to reconnect roads and railways across the border with North Korea.

Presidential spokesman Kim Eui-kyeom made the remark, rejecting a media report that Seoul and Washington are out of sync with each other on the road and rail project after the U.S. State Department said improvements in inter-Korean relations cannot move separately from resolving the North Korea nuclear issue.

"The South and the U.S. are maintaining the highest level of cooperation," Kim told reporters. "The rail and road issue is moving well as scheduled, and we're communicating closely with the United States too."

Kim said he checked the State Department's original comment and found that it's a line that the department has used dozens of times before whenever asked for comments. President Moon also made the same remark before, Kim said.

Moon and North Korean leader Kim Jong-un agreed at their third summit last month to reconnect two sets of cross-border roads and railways. On Monday, the two sides held high-level talks and agreed to hold a groundbreaking ceremony sometime between late November and early December.
