In response to Washington launching a flurry of Section 301 investigations targeting China on the false grounds of "overcapacity", Beijing's reply has been resolute.

In a rules-based counterpunch, China's Ministry of Commerce has initiated trade barrier investigations, meticulously documenting the practices of the United States that restrict high-tech exports, curb bilateral investment and impede the flow of green products. Beijing is defending the legitimate rights and interests of Chinese enterprises — and it is doing so on the basis of multilateral rules. By extension, it is also upholding the authority of the World Trade Organization, an institution Washington has spent much of the past decade systematically undermining.

The latest round of tit-for-tat moves between the world's top two economies has raised the consequential question: will the global economic order be governed by rules or by force?

The world economy is undergoing a profound structural shift. Digitalization and decarbonization are reshaping production, supply chains and comparative advantages. In such an environment, the temptation for some economies to tilt the playing field in their favor is considerable. So too is the risk that, in doing so, they corrode the very system that enabled their rise.

The US has grown accustomed to weaponizing the dollar and repurposing supply chains as instruments of geopolitical leverage. This has created a negative demonstrative effect, prompting some countries to raise the following questions: If Washington can erect barriers in the name of "national security", why can't we? Should others remain bound by rules that the US itself appears willing to disregard?

US investigations purport to address "unfair" trade practices, yet the preliminary evidence compiled by Beijing, for instance, suggests a pattern of obstruction that is difficult to dismiss. From delays to new energy projects to restrictions on technological cooperation in green sectors, US measures reflect a deep anxiety: the fear of losing its edge in the innovation race. Increasingly, Washington appears less focused on winning through invention than on securing advantage through prohibitions.

But the world has changed. When Washington decries "overcapacity", much of the developing world hears something else: affordable green technology and products. When the US blocks Chinese electric vehicles and solar panels, it is not simply shielding domestic industry; it is slowing the global energy transition. In treating economic globalization as a zero-sum contest, the US risks forfeiting the moral high ground it once claimed.

Beijing, by contrast, is positioning itself as a champion of continuity. Chinese officials, be it in Hainan province at the Boao Forum for Asia Annual Conference or at the WTO Ministerial Conference in Yaounde, capital of Cameroon, last week, for example, repeat a consistent theme: that China's development offers a measure of certainty in an uncertain world. While parts of the West retreat into protectionism, China remains a staunch defender of an open, rules-based trading system.

The mechanics of the current dispute are revealing. China's Ministry of Commerce has allowed itself six months to complete its investigations. Depending on the findings, it could pursue diplomatic negotiations, reciprocal countermeasures or litigation through the WTO.

By contrast, Washington still appears to view tariffs and unilateral measures as its primary levers. Yet even within the US policy community, there is a growing recognition that such tools are blunt instruments in a finely balanced global system.

The language of "non-vicious competition", invoked by China's Commerce Minister Wang Wentao in discussions with US Trade Representative Jamieson Greer, on the sidelines of the WTO meeting, may sound aspirational, but it points to a pragmatic truth: rivalry need not preclude cooperation.

What is ultimately at stake is not the bilateral trade balance or even the fate of specific industries. It is the future of global economic governance. For all its flaws, the multilateral trading system remains the only viable framework capable of managing a world in which supply chains span continents and technologies diffuse at speed. If the US continues to treat that system as a "threat", it risks isolating itself from the very order that helps the US prosper.

China, meanwhile, is playing a longer game. Its economic planning is continuous, its policy direction stable and its vision of modernization explicitly addresses the "unbalanced development" that continues to divide the global economy. In areas ranging from digital infrastructure to green technology, it is offering a path that resonates — particularly among countries that feel underserved by the existing global institutions.

The pertinent question now is whether the US will adapt to the changing world — or find itself increasingly out of step with the order it once built.
