In this Wednesday, June 22, 2016, photo, factory workers operate sewing machines at a shoe factory in Wonsan, North Korea. For the past few weeks, North Koreans across the nation have been mobilized for a 200-day “speed campaign” in line with their leader Kim Jong Un's vows to raise the nation's standard of living and energize his new five-year plan to develop the economy. At the direction of Kim Jong Un, who visited the factory last November, workers are now focusing on making lighter, better quality shoes and providing a wider variety to make North Korea's shoe production “world class” before the five-year plan ends.
