North Korea has abolished key government organizations tasked with managing relations with South Korea, state media said Tuesday, as authoritarian leader Kim Jong-un said he would no longer pursue reconciliation with his rival.

North Korea’s official Korean Central News Agency said the decision to abolish the agencies handling dialogue and cooperation with the South was made during a meeting of the country’s rubber-stamp parliament on Monday.

The Supreme People’s Assembly said in a statement that the two Koreas were now locked in an “acute confrontation” and that it would be a serious mistake for the North to regard the South as a partner in diplomacy.

North Korea earlier this month fired a barrage of artillery shells near the disputed western sea boundary with South Korea, prompting the South to conduct similar firing exercises in the area. Kim has also released verbal threats, using a political conference last week to define South Korea as the North’s “principal enemy” and threatened to annihilate it if provoked.
