Functioning of Socialist States: China, Cuba, and Vietnam

When most people hear the word “socialism,” they picture state factories, ration queues, and a single party controlling everything. Yet the socialist states that survive today look surprisingly different from that image. China hosts more billionaires than almost any other country. Vietnam runs a stock exchange and courts foreign investors. Cuba has begun licensing private restaurants. So what makes a state “socialist” in the twenty-first century, and how do these governments actually function? The answer lies less in the economy and more in who holds political power. Across China, Cuba, and Vietnam, a single communist party controls the state, the military, and the levers of society, even where markets have been allowed to flourish.

What defines a socialist state 🔗

A socialist state is a country constitutionally committed to building socialism, usually governed by a single Marxist-Leninist communist party. In Western academic writing these are often called “communist states,” even though their own constitutions describe them as socialist republics still in the process of building socialism on the road to a future communist society.

The organising principle behind all three of our examples is the vanguard party. This idea comes from Vladimir Lenin, who argued that a disciplined, centralised party of professional revolutionaries was needed to lead the working class. In a Marxist-Leninist state, this vanguard party holds a monopoly on political power and acts as the leading force in all aspects of society, including the economy, military, and cultural institutions.

The party operates through a method called democratic centralism. Members can debate internally, but once a decision is made everyone must publicly support it. The same principle that keeps the party united also provides a justification for suppressing dissent and concentrating power at the top. Today, Marxism-Leninism remains the ruling ideology in China, Cuba, Laos, and Vietnam, all of which are one-party socialist republics.

China: socialism with Chinese characteristics 🔗

China is the most striking example of how far a socialist state can travel economically while staying politically rigid. For the first three decades after the People’s Republic was founded in 1949, China ran a Soviet-style command economy with centralised planning, collectivised agriculture, and almost no private business. That changed dramatically after 1978.

Market reforms under party control 🔗

The phrase “socialism with Chinese characteristics” was coined by Deng Xiaoping in 1982. It was tied to his programme of adopting elements of market economics to foster growth through foreign investment and higher productivity, while the Communist Party of China (CPC) kept both its formal commitment to communism and its monopoly on political power. The official label for the system is a “socialist market economy,” a phrase that openly acknowledges the tension between markets and socialism rather than resolving it.

In practice, this means state-owned enterprises and private businesses coexist. The introduction of market mechanisms has produced remarkable growth and lifted millions out of poverty, turning China into one of the world’s largest economies. Yet the party never let go of the “commanding heights.” It retains control over key sectors and uses tools of influence even in areas like higher education.

Where the party draws the line 🔗

The constitutional position is unambiguous. China’s constitution declares it a socialist state led by the working class, and a 2018 amendment specified that leadership by the Communist Party is the defining feature of socialism with Chinese characteristics. Economic liberalisation has never been allowed to become political liberalisation.

This is where the harder edge of the state appears. The CPC maintains tight control over political and social life through extensive censorship, with the “Great Firewall” blocking access to many foreign websites, and through sophisticated surveillance of the population. Economic freedom for entrepreneurs has expanded; political freedom for citizens has not.

Cuba: the Soviet-style model 🔗

Cuba represents the opposite end of the spectrum. Where China embraced markets early and aggressively, Cuba clung much longer to the classic Soviet template of central planning and state ownership.

A single-party, state-controlled system 🔗

After the 1959 revolution, the Communist Party of Cuba (PCC) built a planned socialist economy modelled on the Soviet Union. Private entrepreneurship was almost entirely absent for decades. Cuba’s one-party state outlaws political pluralism, bans independent media, and severely restricts basic civil liberties, while the government continues to dominate the economy despite recent reforms.

Power is highly concentrated. Within Cuba’s political structure, the Political Bureau of the PCC functions as the most important decision-making body in the country. The party oversees everything from policy-making to law enforcement, and its influence reaches into education, healthcare, and the media.

Cautious, limited reforms 🔗

Cuba did not stand entirely still. After the Soviet Union collapsed in 1991 and its subsidies disappeared, the island faced severe economic strain. Reforms adopted since 1994 eased controls on private sales and permitted some private services, but the state still directs much of the economy. The biggest step came in September 2021, when the government legalised private micro, small, and medium-sized enterprises for the first time since the 1960s.

Even so, the legal architecture of communism remains intact. The 2019 constitution recognised private property for the first time since the revolution and promoted foreign investment, yet it simultaneously designated private enterprise as playing only a “complementary” role alongside state ownership, which stays the primary form of property. Cuba’s reforms are real but deliberately narrow, never large enough to challenge the dominance of the state.

Vietnam: Doi Moi and the socialist-oriented market economy 🔗

Vietnam offers a middle path that closely mirrors the Chinese experiment, though it began under desperate conditions. In the mid-1980s, Vietnam’s classic socialist economy was crippled by hyperinflation, budget deficits, and shortages of basic goods, with inflation peaking at hundreds of percent.

The 1986 turning point 🔗

In December 1986, at the 6th National Congress of the Communist Party of Vietnam (CPV), the leadership launched Doi Moi, meaning “renovation.” These reforms replaced the centrally planned economy with a market-based mixed economy built around state-owned industry. They introduced market mechanisms, allowed private ownership of small enterprises, and eventually created a stock exchange.

The chosen label is the “socialist-oriented market economy.” The word “oriented” carries real meaning here: the CPV maintains that Vietnam has not yet achieved socialism but is building the foundation for a future socialist system. The model is deliberately similar to China’s socialist market economy.

Economic opening without political opening 🔗

The results have been dramatic. Over roughly three decades, Vietnam moved from being one of the world’s least developed nations to a booming middle-income economy, with poverty falling sharply. Yet, crucially, this economic transformation was never meant to lead to democracy.

Many observers assumed that free markets would eventually bring political freedom. In Vietnam this did not happen. The shift to a socialist-oriented market economy was not a sign that the CPV planned to democratise. In fact, Doi Moi happened largely because the party recognised it needed to adapt economically in order to survive as a one-party regime. The CPV keeps strict control over political life, the media remains state-controlled, and freedom of expression is limited.

Common strategies for consolidating power 🔗

Despite their differences, these three states share a recognisable toolkit for maintaining one-party rule. Understanding these shared patterns matters more than memorising the individual differences.

Control of information 🔗

The first and most consistent strategy is controlling what people see and hear. Censorship of media and restrictions on internet access let these governments shape public perception. This control extends into education, where curricula are designed to promote party ideology. China’s Great Firewall is the most advanced example, but state-controlled media in Cuba and Vietnam serve the same function.

Suppression of dissent 🔗

The second strategy is direct suppression. The democratic centralism that organises the vanguard party also justifies coercion against perceived enemies of the revolution. Across these regimes, individual and collective dissent has historically been either suppressed or confined to internal party discussion. Penalties for open opposition can be severe.

Pragmatic economic reform 🔗

The third and most modern strategy is reform itself. China and Vietnam show that allowing markets can actually strengthen one-party rule rather than weaken it. By delivering rising living standards, the party earns a form of performance-based legitimacy that buys public tolerance for continued political control. Cuba’s slower, more reluctant reforms suggest the same logic, applied with greater caution. For comparative politics students, this is a key insight that distinguishes these regimes from the failed Soviet model: economic flexibility can serve political survival.

What do you think? If allowing markets can actually make a one-party state more stable rather than pushing it toward democracy, should we still expect economic development to bring political freedom? And when a state calls itself “socialist” while billionaires thrive within it, what do you think the word “socialism” really describes in these systems today?
