The 10th Central Committee elected the 10th Politburo and the 10th Secretariat.

The Central Committee (CC) is not a permanent institution.

Instead, it convenes plenary sessions between party congresses.

When the CC is not in session, decision-making powers are delegated to its internal bodies; that is, the Politburo and the Secretariat.

None of these organs are permanent bodies either; typically, they convene several times a month.
