North Korean leader Kim Jong Un urged city and county officials to bring about changes and achievements that can “be appreciated” by the people, state media reported on Sunday.

In his closing remarks for the country’s first-ever “short course” for regional party committee chief secretaries, Kim on March 6 stated that the officials should follow the ruling party’s guiding principles and “vigorously mobilize” the masses for “revolutionary work,” according to the Korean Central News Agency (KCNA). He added that city and council officials should encourage the masses to take the initiative in the “struggle for local development,” KCNA stated.
