North Korean leader Kim Jong Un declared an “intensifying” fight against foreign influence on kids on Monday, instructing mothers to send their children to perform hard labor for the state to correct bad behavior that is not “our style.”

Kim made the remarks on the final day of a large-scale national conference on improving government control over child-raising, an event the leader considers “more important than others” due to its role in ensuring “patriotism and loyalty” to his rule from a young age.
