The 9th Central Committee of the Communist Party of Vietnam was elected at the 9th National Congress of the Communist Party of Vietnam. It elected the 9th Politburo and the 9th 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.
