The Party Congress is a fundamental organizational system of the Party. It is a meeting where the Party organizations at all levels, including the central organization, local organizations at all levels and some grassroots organizations, discuss and decide on major issues of the Party and elect the Party’s leading organs.

The Party Constitution stipulates: “The highest leadership organ of the Party is the Party’s National Congress and the Central Committee arising from it. The Party’s local organs at various levels are the Party’s local congresses and the committees they produce. Party committees at all levels are responsible for and report on their work to the congress at the same level.
