North Korean leader Kim Jong Un has said his country’s education system “lags far behind” the world’s development trends and the ruling party's plans, calling on teachers and officials to rectify these defects "as early as possible," state media reported on Wednesday.

The remarks came in a work titled "Teachers Should Fulfill Their Duty as Career Revolutionaries in Implementing the Party's Policy on Bringing About a Radical Turn in Education" published on the occasion of Tuesday's 14th National Conference of Teachers held in Pyongyang.
