The core driver of U.S.- China competition is the erosion of American hegemony

By Joel Wong

Many credible analysts argue that the core driver of U.S.-China competition is not economic systems or cultural values—but the erosion of American hegemony. The rise of China represents the first serious challenge to U.S. global dominance since the end of the Cold War, and that geopolitical reality—not ideology—is what’s fueling strategic confrontation.

Here’s a breakdown of why hegemony, not just economics or ideology, is at the heart of the U.S.-China rivalry:

1. The End of the “Unipolar Moment”

After the collapse of the Soviet Union in 1991, the U.S. entered what some called the “unipolar moment”—a period when American military, economic, and ideological supremacy was essentially uncontested.

The U.S. shaped global trade rules (WTO), security alliances (NATO), and values (democracy, human rights) with little resistance.
It could enforce its will through sanctions, military intervention, and economic leverage with few consequences.

But China’s rapid rise is now reshaping the balance of power, especially in Asia—and increasingly, around the world.

2. China as a Peer Competitor, Not Just a Trade Partner

For decades, the U.S. viewed China as an economic partner—a factory for American companies and a buyer of U.S. debt. But now:

China has developed indigenous tech, advanced weaponry, and global infrastructure projects (e.g., Belt and Road).
It is building parallel institutions (like the Asian Infrastructure Investment Bank) that reduce dependence on Western-led systems.
Its military expansion and assertiveness in the South China Sea challenge U.S. naval supremacy in the Indo-Pacific.

In short, China is no longer just “rising”—it’s competing, and in some arenas, surpassing.

3. U.S. Anxiety: Losing the Power to Set the Rules

The greatest fear in Washington is not just economic competition—it’s the loss of control over the international order. This includes:

Losing the U.S. dollar’s dominance in global trade.
Being outflanked in setting technology standards (e.g., 5G, AI).
Seeing international institutions (like the UN, IMF) bend toward Chinese preferences.
Fewer countries siding with the U.S. in geopolitical disputes (e.g., over Taiwan, Gaza, Ukraine).

The U.S. sees its strategic leadership slipping—and is reacting accordingly.

4. Containment, Not Conversion

In the 1990s and 2000s, the goal was to integrate China into the U.S.-led liberal order. That strategy has shifted.

Today, U.S. policy has moved toward containment:

Tech bans and export controls (semiconductors, AI chips).
Military alliances in Asia (AUKUS, Quad, bases in the Philippines).
Rhetoric framing the rivalry as “democracy vs. autocracy.”

But these moves are not about changing China’s political system—they’re about preserving U.S. primacy.

5. This Is a Hegemonic Transition, Not a Cultural Clash

While cultural and ideological differences exist (individualism vs. collectivism, liberalism vs. authoritarianism), they are secondary to the power struggle.

The U.S. had close trade relations with authoritarian regimes for decades (e.g., Saudi Arabia) without triggering cold wars.
The real problem is that China is strong enough to challenge U.S. dominance—and unwilling to play by Washington’s rules.

In other words: If China were a poor authoritarian state, the U.S. wouldn’t care. It’s because China is a rich, powerful authoritarian state that it’s a problem.

6. Hegemonic Decline Is Painful—and Dangerous

History shows that declining hegemons often respond aggressively to rising powers. The U.S. is no exception:

It is trying to retain dominance, not necessarily through cooperation, but through confrontation.
This increases the risk of proxy conflicts, trade wars, or even direct military escalation, particularly over Taiwan or sea lanes.

The underlying dynamic is Thucydides’ Trap: the idea that war becomes likely when a rising power threatens to displace an established one.

Conclusion: Power, Not Philosophy

So while values and systems matter, the heart of the U.S.-China conflict is about power: who leads the world, who sets the rules, and who gets to shape the future. The U.S. is not just reacting to a different system—it is reacting to the possibility that its hegemonic era is ending, and that China may build a world order where America is no longer at the center.
