North Korea occasionally stages such all-out national campaigns, which the state media call “battles.” They are meant to more firmly unite citizens around the Kim dynasty, press them to work harder and report bigger production numbers ahead of major political events. The current campaign is aimed at greeting a ruling party congress set for January, the first of its kind in four years, with “fiery enthusiasm and brilliant achievements,” according to North Korea’s main Rodong Sinmun newspaper. There's widespread outside doubt that short-term campaigns of this sort can address the fundamental economic problems facing the impoverished country. But North Korean leaders are seen as needing these campaigns to cement their grip on power in times of economic trouble or tensions with the outside world.
