A socialist state, socialist republic, or socialist country, sometimes referred to as a workers' state or workers' republic, is a sovereign state constitutionally dedicated to the establishment of socialism. The term communist state is often used synonymously in the West, specifically when referring to one-party socialist states governed by Marxist–Leninist communist parties, despite these countries being officially socialist states in the process of building socialism and progressing toward a communist society. These countries never describe themselves as communist nor as having implemented a communist society. Additionally, a number of countries that are multi-party capitalist states make references to socialism in their constitutions, in most cases alluding to the building of a socialist society, naming socialism, claiming to be a socialist state, or including the term people's republic or socialist republic in their country's full name, although this does not necessarily reflect the structure and development paths of these countries' political and economic systems. Currently, these countries include Algeria, Bangladesh, Guyana, India, Nepal, Nicaragua, Sri Lanka and Tanzania.

Ho Chi Minh Thought is a political philosophy that builds upon Marxism–Leninism and the ideology of Vietnamese revolutionary Ho Chi Minh. It was developed and codified by the Communist Party of Vietnam and formalised in 1991. The term is used to cover political theories and policies considered as representing a form of Marxism–Leninism that has been adapted to Vietnamese circumstances and history. The ideology includes views on the basic issues of the Vietnamese Revolution, specifically the development and application of Marxism–Leninism to the material conditions of Vietnam.
