South Korea said Monday that the abrupt cancelation of United States Secretary of State Mike Pompeo's trip to North Korea is having an "effect" on a controversial inter-Korean liaison office it planned to open by this month.

U.S. President Donald Trump abruptly canceled his top diplomat's planned trip to North Korea on Friday, publicly acknowledging for the first time that his effort to get Pyongyang to denuclearize had stalled since his summit with the North's leader in June.

South Korea's presidential Blue House spokesman Kim Eui-kyeom said Monday that the canceled visit "cannot be said to have zero effect" on the plan for the liaison office.
