Four pillars (Vietnam)
The four pillars (Vietnamese: bộ tứ, or tứ trụ), also known as five pillars (ngũ trụ), are the most important party-state positions in the Communist Party of Vietnam and the government of Vietnam: the General Secretary of the Communist Party of Vietnam, President of Vietnam, Prime Minister of Vietnam, Chairman of the National Assembly of Vietnam, and the Permanent Member of the Secretariat. Together, they are officially designated as the "Key Leaders of the Party and the State" (Vietnamese: Lãnh đạo chủ chốt của Đảng và Nhà nước) and can be considered as the de facto highest state leaders.
