To better the institution building of the CPC, various documents have been adopted since the 18th National Congress of the CPC.

A plan to deepen institutional reforms on Party building was approved by the Party's core leadership, the Political Bureau of the CPC Central Committee.

At the sixth plenary session of the 18th CPC Central Committee last November, an updated norm of political life and a regulation on intra-Party supervision was approved. The two important documents were implemented in January 2016.
