North Korea’s elite warned that the country’s political system could collapse if lower-level leaders don’t improve their ideological unity, state media reported on Wednesday after officials gathered for the second day of a Pyongyang conference.

Like on the first day of the conference, speakers from factories and organizations across the country were summoned to tell a reported crowd of 10,000 people about their achievements or failures at the Sixth Conference of Cell Secretaries. Several of these secretaries stressed the importance of becoming “ardent loyalists” to the country’s leader, Kim Jong Un, in their speeches.
