Trade Wars and Protectionism

The idea of free trade is often celebrated as the lifeblood of globalization. Nations open their markets, reduce tariffs, and pledge allegiance to the invisible hand of Adam Smith. Yet behind the rhetoric of liberal economics lies the enduring instinct of states to protect their own. This instinct protectionism has never disappeared. It resurfaces in every age, and today it finds its sharpest expression in the trade war between the United States and China.

Trade Wars as Modern Battlefields

A trade war is not fought with tanks and missiles but with tariffs, sanctions, and restrictions. It is war nonetheless, because its purpose is the same: to weaken the adversary, preserve dominance, and secure national interest. The U.S.–China conflict, beginning under the Trump administration, laid bare this reality.

Washington accused Beijing of intellectual property theft, currency manipulation, and unfair subsidies to its industries. China countered with tariffs of its own, targeting American agricultural exports and high-value goods. The exchange escalated into a spiral of protectionist measures, each side justifying its actions in the language of sovereignty and economic survival.

This was not simply a quarrel about steel, soybeans, or smartphones. It was a clash of two models: American capitalism built on free-market rhetoric, and Chinese state capitalism designed to tilt the playing field in favor of national champions.

Protectionism is often dismissed as regressive, a betrayal of the global order. But to dismiss it is to misunderstand its function. Protectionism emerges when states feel threatened, when the costs of openness outweigh the benefits, when interdependence begins to look like vulnerability.

For the U.S., globalization enriched China far more quickly than it expected. The very supply chains that once fueled American corporations made the U.S. economy dependent on Chinese labor, manufacturing, and rare earths. For China, protectionism has always been a developmental tool. It shielded its industries until they became global competitors Huawei, Alibaba, and countless others.

Thus, protectionism is not a rejection of globalization but a tactic within it. It is the pause button states press when they fear they are losing the game.

Tariffs as Weapons

In this trade war, tariffs functioned like artillery fire. The U.S. imposed duties on hundreds of billions of dollars’ worth of Chinese imports, hoping to make them less competitive and to push companies to relocate production. China retaliated with tariffs on American goods, striking directly at U.S. farmers in an attempt to create political pressure within Trump’s base.

Every tariff was not just an economic measure but a message: “We will not be dominated.” In this sense, the trade war exposed the reality that economics cannot be separated from politics. Free trade is never entirely free; it is always shaped by the power of states to intervene.

Some argue that trade wars are self-defeating because they raise prices, disrupt supply chains, and hurt consumers. While true in the short run, states often accept this pain for long-term gain. The U.S. sought to slow China’s technological rise. China sought to resist American dominance. Both believed that without protectionism, their future sovereignty was at risk.

This is why the logic of protectionism is stronger than the logic of free trade. Free trade assumes trust, cooperation, and shared benefit. Protectionism assumes rivalry, suspicion, and survival. History shows us which instinct usually prevails.

The U.S.–China trade war was never just about goods. It was about who would set the rules of the 21st-century economy. Technology, data, and artificial intelligence became battlegrounds. Huawei was banned, TikTok scrutinized, semiconductors restricted. Protectionism extended into cyberspace and innovation.

This reveals a deeper truth: trade wars are only the visible layer of a geopolitical contest. Protectionism becomes the shield states raise as they prepare for larger confrontations in ideology, security, and influence.

Protectionism: Vice or Virtue?

From a philosophical standpoint, protectionism can be seen as both vice and virtue. As vice, it limits cooperation, inflates costs, and stifles innovation. As virtue, it preserves sovereignty, nurtures domestic industries, and prevents dependency on rivals.

The U.S.–China trade war embodies this paradox. Each side condemned the other’s protectionism while defending its own. Each spoke of “fairness” while practicing calculated self-interest. And this hypocrisy is the essence of international politics: principles become negotiable, interests do not.

Trade wars, like the one between the United States and China, reveal that globalization is not a peaceful utopia but a contested space where power defines fairness. Protectionism, far from being an outdated relic, is the weapon states reach for when they feel threatened.

The world may chant slogans of free markets, but the reality remains: nations do not trade for ideals they trade for advantage. And when advantage is threatened, the walls of tariffs rise, proving that protectionism is not the opposite of globalization but its permanent shadow.
