North Korean leader Kim Jong-un presided over a politburo session of the Workers' Party in his first public appearance in a month and discussed convening a key party meeting and organizational matters, state media said Saturday.

During the session, the North decided to hold a plenary meeting of the Central Committee of the Party in early June to take "additional state measures for solving pending problems urgent for the economic work and people's living," the official Korean Central News Agency said.

"Positively appreciating that a lot of planned works are being sped up on a long-term basis ... the respected General Secretary briefed and analyzed the execution of major policy tasks in different fields for the first half of the year," KCNA said.

Kim said that the plenary meeting will be held to review the overall state affairs for the first half of the year to take measures to correct mistakes and "deflective matters."

The meeting also discussed the structural reorganization of departments of the Central Committee of the Party and other agendas for the upcoming plenary meeting.

Kim was last seen in public on May 6 when he held a photo session with families of the North's army after watching their performance the previous day. (Yonhap)
