SEOUL, South Korea (AP) — North Korean leader Kim Jong Un dismissed a vice premier in charge of the country's machine-building industry, state media reported Tuesday, in an apparent bid to strengthen discipline among senior officials ahead of the upcoming ruling Workers’ Party congress to establish new economic and other state objectives.

The Korean Central News Agency said that Kim blamed Yang Sung Ho for causing “unnecessary man-made confusion†in a speech marking the completion of a first-stage modernization project at the Ryongsong Machine Complex in the northeast on Monday.
