K’ONYANGO: Why protectionism endangers global growth and shared prosperity

In an era marked by economic uncertainty and geopolitical strain, the debate over protectionism has returned with renewed intensity. At the centre of this discussion stands Asian giant, one of the world’s largest trading nations and a central pillar of global supply chains.

As barriers rise in parts of the world, Beijing’s continued advocacy for open markets places it squarely within a defining question of our time: will the global economy fragment into guarded blocs, or will it remain interconnected and cooperative?

The resurgence of protectionist policies is often framed as a defence of domestic industry. Tariffs, subsidies and regulatory hurdles are presented as shields against unfair competition.

Yet history and contemporary evidence suggest that such measures rarely deliver the promised revival. Instead, they distort markets, inflate costs and trigger retaliatory responses.

In a deeply interdependent global system, no major economy can insulate itself from these consequences. China’s experience as both a major exporter and importer underscores how integrated modern production has become, with components crossing borders multiple times before reaching consumers.

When countries impose higher tariffs or tighten trade restrictions, the impact reverberates through supply chains. Manufacturers face higher input costs. Small businesses struggle to absorb price increases.

Consumers pay more for everyday goods. Financial markets react to uncertainty, dampening investment and slowing expansion. Protectionism does not simply target foreign competitors. It often burdens domestic firms that rely on global networks for efficiency and innovation.

China’s position in global trade illustrates this dynamic clearly. Over the past decades, its growth has been closely tied to participation in international markets.

At the same time, China has become a significant destination for imports, from agricultural products to advanced machinery and services. This two-way flow reflects the reality that trade is not a zero-sum contest. It is an exchange that, when governed by fair and transparent rules, generates mutual benefit.

The broader global context makes protectionism even more risky. The world faces overlapping challenges that transcend borders. Climate change demands coordinated investment in renewable energy and green technology.

Public health crises require rapid sharing of medical supplies and scientific knowledge. Digital transformation depends on cross border data flows and collaborative innovation. Fragmenting the global economy through barriers makes collective responses more difficult and more costly.

Multilateral institutions remain essential in this landscape. Frameworks that encourage dialogue, dispute resolution and rule-based trade help prevent tensions from escalating into destructive cycles. When countries commit to shared norms, businesses gain predictability and smaller economies gain a voice.

China has repeatedly emphasised the importance of maintaining and reforming these institutions rather than abandoning them. A stable global trading system benefits all participants, particularly in times of volatility.

It is also important to recognise the developmental dimension of open trade. Emerging economies across Africa, Asia, and Latin America have integrated into global value chains as producers of manufactured goods, technology services, and processed agricultural products.

Access to large markets allows them to scale up industries, create jobs, and attract foreign investment. Rising protectionism threatens to close off these pathways. For developing nations striving to move up the value chain, shrinking market access can stall progress and entrench inequality.

The argument against protectionism is not a call for unregulated markets. Thoughtful policy can address legitimate concerns about labour standards, environmental protection, and unfair practices. Domestic adjustment programs, worker retraining, and targeted support for strategic sectors are more effective than sweeping tariffs that raise prices across the board.

The challenge for policymakers is to balance competitiveness with openness, ensuring that economies remain resilient without retreating into isolation.

China’s continued engagement in global trade highlights an alternative vision. Rather than framing economic relations primarily through confrontation, it emphasises connectivity, infrastructure development, and market integration. While debates persist over specific policies and practices, the larger principle remains clear: sustained growth depends on interaction, not withdrawal.

Protectionism may offer the illusion of control in an unpredictable world. It can be politically appealing to promise immediate relief through barriers.

Yet the long-term costs often outweigh the short-term gains. Reduced trade volumes mean slower productivity growth. Higher consumer prices erode purchasing power. Strained relationships weaken the cooperative spirit needed to tackle global crises.

The price of barriers is ultimately paid by everyone. In contrast, open and predictable trade fosters innovation, spreads opportunity, and strengthens resilience. As one of the world’s major economic actors, China’s stake in this outcome is considerable, but the implications extend far beyond any single country.

The choice facing the international community is stark. Retreat into fragmented blocs and accept diminished growth, or recommit to multilateralism and shared prosperity. The evidence, both historical and contemporary, points clearly toward cooperation as the more sustainable path forward.
