The presidential office is trying to figure out the intentions of North Korea in relation to its abrupt cancellation of high-level inter-Korean talks set for Wednesday. 

Seoul's Unification Ministry was informed of the meeting's "indefinite postponement" just after midnight in a notice sent by Ri Son-gwon, chairman of the Committee for the Peaceful Reunification of the Country, which handles relations with the South. 

A senior presidential official told reporters that the top office's security officials closely discussed the sudden cancellation with the related ministries of unification, foreign affairs and defense on the phone. 

The official added that the government is focusing its efforts on figuring out the exact meaning of the notice, adding it has no plan to change the schedule or the scope of the ongoing Max Thunder air drill between the U.S. and South Korea, which the North cited as its reason for cancelling the planned inter-Korean talks.
