North Korea’s parliament has conferred a new title on its leader Kim Jong-un as the head of a newly-established top governing body.

The North’s Korean Central Television Wednesday night reported about the 13th Supreme People’s Assembly in Pyongyang, during which the young leader was appointed as the head of the "state affairs commission.”

The state affairs commission replaces the National Defense Commission, which Kim led as the chairman.

Seoul’s Ministry of Unification said the latest gathering of the rubber-stamp parliament was aimed at completing efforts to build its monolithic leadership, following the seventh congress of the North’s ruling Workers’ Party in May.

During the May event, Kim was unanimously elected as the "Chairman of the Workers' Party," a position once held by North Korean founder Kim Il-sung.

Kim now holds the office in which he is able to wield power over the military and a wide range of national affairs as well as the party.

According to the unification ministry, the newly-established committee will not only absorb the responsibilities assumed by the National Defense Commission, but also make a decision on many non-military issues, including diplomacy, inter-Korean relations, and the economy.

The Supreme People’s Assembly session further highlighted the concentration of Kim’s monolithic power by filling the deputy positions of the new committee with the officials who have taken charge of different areas.

Another noticeable change the latest assembly session brought to the North’s power structure was the promotion of the North’s Committee for the Peaceful Reunification of Korea.

The committee, which has handled the North’s policies on inter-Korean exchanges, is now a central government body.

Seoul experts say this change could lead Pyongyang to take a friendlier approach toward the South as the North is suffering from the toughened international sanctions over its nuclear and missile tests.
