No director-level meetings have been held at an inter-Korean liaison office at Kaesong for almost two months, South Korea's Ministry of Unification (MOU) confirmed on Friday, in a further sign of a deepening diplomatic impasse between Seoul and Pyongyang in the aftermath of February's failed U.S.-DPRK summit in Hanoi.

Seoul and Pyongyang previously agreed to hold weekly meetings between their respective directors of the round-the-clock liaison office, though talks have not been held since February 22.
