The central question is no longer simply how much the United States imports from China, or how much China exports to America. It is increasingly about who controls the technologies, resources, financial networks, manufacturing capabilities and standards on which the global economy depends.
Semiconductors sit at the centre of this contest. Artificial intelligence is expanding it into computing, data and software. Rare earths have demonstrated how control over upstream materials can become geopolitical leverage. US sanctions and dollar-based financial infrastructure provide Washington with a different form of power: the ability to restrict access to markets, technology and financial services. China, meanwhile, is building alternative technological and financial capabilities while using its position in critical supply chains to reduce vulnerability and increase leverage.
The result is a new form of economic competition in which dependency itself has become a strategic asset, and a strategic vulnerability.
The International Monetary Fund has warned that geopolitical rivalry is challenging the assumptions underpinning the multilateral trading system. Its 2026 analysis describes a world in which governments increasingly use tariffs, export controls and restrictions on critical technologies to pursue geopolitical objectives.
For businesses, this changes the meaning of supply-chain risk.
A supplier is no longer simply a supplier. A chip, mineral, payment system, cloud platform, software stack or technical standard can become a point of geopolitical exposure.
The US-China rivalry is therefore evolving from a contest over market access into a contest over economic infrastructure.
The Strategic Shift
For much of the past three decades, US-China economic competition operated within an increasingly integrated global trading system.
American companies gained access to Chinese manufacturing capacity and a rapidly expanding consumer market. China gained access to Western capital, technology, markets and global supply chains.
The relationship was competitive, but interdependence remained economically valuable to both sides.
That model is now being reconfigured.
Washington increasingly views certain economic dependencies as national-security vulnerabilities. Beijing increasingly views technological and financial dependence on Western systems as a strategic risk.
The consequence is not necessarily complete economic decoupling.
Instead, the emerging model is selective interdependence.
Countries may continue trading extensively while attempting to control the technologies, materials and infrastructure that have the greatest strategic importance.
This distinction is critical.
The objective is no longer to eliminate economic interdependence.
It is to ensure that the other side cannot easily weaponise it.
Why It Matters
1. Semiconductors Have Become Strategic Infrastructure
The semiconductor industry illustrates the transformation better than almost any other sector.
Advanced chips are essential to artificial intelligence, cloud computing, telecommunications, autonomous systems, advanced manufacturing and modern defence technologies.
That makes control over semiconductor production and the equipment required to manufacture advanced chips a strategic issue rather than simply an industrial-policy concern.
The United States has progressively tightened restrictions on China's access to advanced computing chips, semiconductor manufacturing equipment and related technologies. In December 2024, the US Department of Commerce expanded controls to additional semiconductor manufacturing equipment, software and high-bandwidth memory, while adding 140 Chinese entities to the Entity List.
The policy has continued to evolve.
In January 2026, the US introduced a case-by-case licensing framework for certain advanced Nvidia and AMD chips, demonstrating that Washington's objective is not simply to eliminate technology trade with China but to manage which technologies can flow, to whom and under what conditions.
The United States is also using tariffs as part of its industrial strategy. A January 2026 presidential proclamation established a 25% tariff on covered semiconductor imports, with exemptions for certain strategic uses and provisions intended to encourage domestic technology supply-chain investment.
The direction is clear: access to computing capacity is becoming a geopolitical instrument.
2. Artificial Intelligence Is Turning Computing Power into Economic Power
The semiconductor contest is increasingly inseparable from the AI race.
AI requires advanced processors, data centres, electricity, networking infrastructure, specialised software and enormous pools of capital.
Control over any one of these layers can influence the competitiveness of entire industries.
China's 2026 five-year planning process explicitly elevated AI and advanced technologies, with Beijing targeting breakthroughs in AI, quantum computing, 6G and humanoid robotics while expanding AI deployment across manufacturing, logistics, healthcare and other sectors.
At the same time, US restrictions are designed to constrain China's ability to obtain or produce the most advanced computing technologies.
The competition is consequently becoming broader than a race between individual AI companies.
It is a competition over the industrial stack required to operate an AI economy.
That includes:
advanced chips;
semiconductor manufacturing equipment;
high-bandwidth memory;
data centres;
cloud infrastructure;
energy generation;
AI models;
data;
telecommunications networks;
cybersecurity;
technical standards.
This creates a new strategic reality for corporations.
AI strategy can no longer be separated entirely from geopolitical strategy.
3. Rare Earths Demonstrate the Power of Upstream Control
If semiconductors demonstrate the power of technological chokepoints, rare earths demonstrate the power of resource concentration.
China's April 2025 export controls placed restrictions on several medium and heavy rare earth elements and related products, including samarium, gadolinium, terbium, dysprosium, lutetium, scandium and yttrium. Exporters must obtain licences under China's export-control framework.
The importance of these controls extends well beyond mining.
Rare earths are embedded in advanced magnets, electronics, aerospace systems, defence technologies and other high-performance industrial applications.
By May 2026, Reuters reported that China's controls were still affecting shipments of materials including yttrium, dysprosium and terbium, with some exports to the United States significantly below previous levels despite efforts to ease the disruption.
The strategic lesson is important.
Control does not require ownership of the entire global industry.
A country can exert considerable influence by controlling a critical stage through which the rest of the supply chain must pass.
That principle applies equally to minerals, chips, financial messaging systems, cloud infrastructure and technical standards.
4. Sanctions Turn Financial Infrastructure into Strategic Power
The United States possesses a different form of economic leverage.
Its influence derives not only from the size of the American economy but from the central position of the US dollar and American-linked financial infrastructure within global commerce.
Sanctions can therefore impose costs without requiring conventional trade restrictions.
The ability to restrict access to dollar-based financial markets, financial institutions and international transactions gives Washington a powerful mechanism for influencing the behaviour of companies and governments outside the United States.
The broader sanctions environment illustrates this increasingly expansive approach. In 2026, US authorities have continued targeting networks involving Chinese and Hong Kong entities where they are judged to facilitate sanctioned activities.
For multinational companies, the implication is profound.
A business can face geopolitical exposure even when neither its headquarters nor its primary customers are located in the United States or China.
Its exposure may instead arise from:
dollar transactions;
US-origin technology;
software licences;
semiconductor components;
financial counterparties;
shipping routes;
sanctioned customers;
controlled subsidiaries.
Financial compliance is therefore becoming part of strategic supply-chain management.
5. China Is Building Against Dependency
Beijing's response is not simply retaliation.
It is also an effort to reduce China's vulnerability to foreign technological and financial pressure.
The IMF's 2026 assessment of China notes the growth of cross-border payment infrastructure, including the Cross-Border Interbank Payment System (CIPS), and the expansion of RMB clearing arrangements. The IMF also notes that rising trade tensions have encouraged Chinese companies to use the RMB more extensively in international transactions.
This does not mean the renminbi is about to replace the dollar as the dominant global currency.
That conclusion would be premature.
The more significant development is that China is building optionality.
If Chinese firms can settle more transactions in RMB, access domestic technology alternatives and diversify export markets, their exposure to external pressure decreases.
That is strategically valuable even without creating a fully independent alternative global system.
The Contest Is Moving into Technology Standards
Economic power is not determined only by who manufactures products.
It is also determined by who defines the standards that products must follow.
Telecommunications, artificial intelligence, wireless connectivity, data governance, cybersecurity and industrial software all depend upon technical standards.
Companies that control or influence standards can shape markets long after individual products become obsolete.
The continuing importance of Chinese technology companies in global standards illustrates this dynamic. In August 2026, Huawei and HP entered a multi-year cross-licensing agreement covering Wi-Fi technology, including Wi-Fi 7, highlighting the continuing importance of standard-essential patents even amid broader US-China technology restrictions.
The strategic competition is therefore moving into an increasingly technical domain:
Who defines the rules by which future technologies communicate, operate and interoperate?
That question matters because standards create network effects.
Once a standard becomes dominant, changing it becomes expensive.
From Supply Chains to Strategic Chains
The traditional supply-chain model prioritised:
cost → efficiency → scale
The emerging model increasingly prioritises:
security → resilience → control → efficiency
This does not mean corporations are abandoning cost considerations.
It means cost is no longer the only variable.
A supplier that is 10% cheaper but exposed to sanctions, export controls or geopolitical disruption may ultimately be more expensive than a higher-cost supplier located in a politically aligned market.
This is why multinational corporations are increasingly examining supply chains through the concept of strategic dependency.
The IMF's recent geoeconomic research captures the underlying problem: globalisation creates efficiency through specialisation, but that same specialisation can produce dependencies that governments can weaponise.
The strategic question for executives is therefore changing from:
Where can we source this product most cheaply?
to:
Which dependencies could prevent us from sourcing this product at all?
Who It Affects
Multinational Corporations
Companies operating across the US and Chinese ecosystems face increasing compliance and supply-chain complexity.
Businesses must understand not only where their products are manufactured but where critical technologies, components, intellectual property and financing originate.
A company may have a geographically diversified supply chain and still possess a concentrated technological dependency.
Technology Companies
Semiconductor designers, cloud providers, AI developers, telecoms firms and data-centre operators are increasingly exposed to national-security regulation.
Technology companies will need to anticipate regulatory changes rather than simply respond to them.
Financial Institutions
Banks and investment firms face growing sanctions, compliance and counterparty risks.
Cross-border financial infrastructure is becoming more politically sensitive, particularly where transactions involve strategic technologies, sanctioned entities or jurisdictions caught between competing geopolitical blocs.
Manufacturers
Industrial companies face a growing requirement to map critical inputs.
Rare earths, advanced chips, industrial software, machine tools and specialised components may become strategic bottlenecks even when they represent only a small percentage of total production costs.
Emerging Markets
The US-China rivalry creates both risks and opportunities for countries outside the two major powers.
Manufacturing diversification could attract investment into countries capable of offering competitive labour, resources, infrastructure and political stability.
But emerging markets may also face pressure to align with one technology ecosystem or the other.
The ability to maintain strategic flexibility could therefore become an important source of economic value.
Where the Opportunity Is
The fragmentation of global supply chains is creating new opportunities for countries positioned between the major economic blocs.
Several areas deserve particular attention.
Critical Minerals
Countries with deposits of rare earths, lithium, cobalt, copper, graphite and other strategic minerals could attract significant investment as companies seek supply diversification.
But extraction alone may not be sufficient.
The greater opportunity lies in developing processing, refining and component manufacturing capabilities.
Semiconductor Supply Chains
Complete semiconductor independence is unrealistic for most countries.
However, specialised opportunities exist in packaging, testing, materials, equipment maintenance, electronics assembly and supporting industrial infrastructure.
Countries that develop capabilities in these segments can integrate into global semiconductor value chains without attempting to replicate the entire industry.
Data Centres and Digital Infrastructure
AI expansion requires enormous amounts of computing capacity and electricity.
Countries with reliable energy, connectivity and regulatory environments could attract data-centre investment and become regional computing hubs.
For Africa, this creates an opportunity to connect digital infrastructure investment with renewable energy development and industrialisation.
Industrial Manufacturing
As companies diversify away from concentrated production networks, countries capable of providing predictable regulation, reliable power, skilled workers and efficient logistics may attract new manufacturing activity.
The opportunity is strongest where governments can offer more than tax incentives.
They must provide an ecosystem.
Strategic Risks
Fragmentation Could Become More Expensive Than Protection
The primary risk is that strategic competition becomes so extensive that economic efficiency is subordinated to geopolitical alignment.
Duplicating supply chains across competing blocs can increase costs, reduce economies of scale and slow technological diffusion.
The IMF has warned that the return of geopolitics threatens the assumptions on which decades of trade integration were built.
The objective for policymakers should therefore be targeted resilience rather than indiscriminate decoupling.
Technology Controls Can Accelerate Technological Substitution
Restrictions may slow a competitor in the short term while encouraging it to develop alternatives in the long term.
China's increasing investment in domestic semiconductor, AI and digital capabilities illustrates this dynamic.
The strategic effectiveness of export controls will therefore depend not only on what technology is restricted today but on whether restrictions accelerate the development of substitutes tomorrow.
Corporate Planning Horizons Are Becoming Shorter
Businesses traditionally plan capital investments over five, ten or twenty years.
Geopolitical regulation can now change much faster.
A technology considered commercially available today can become restricted tomorrow.
That increases the value of scenario planning, regulatory monitoring and flexible capital allocation.
What Decision-Makers Should Do Next
1. Map Strategic Dependencies
Executives should identify the technologies, materials, financial systems and suppliers that their businesses cannot easily replace.
The objective should be to distinguish ordinary supply-chain risks from strategic chokepoints.
2. Build Selective Redundancy
Complete duplication is expensive.
Companies should instead prioritise redundancy around the most consequential dependencies.
Two suppliers may be sufficient for a critical component where a third supplier would add little resilience.
3. Treat Geopolitical Risk as a Board-Level Issue
US-China policy should no longer sit exclusively with government-affairs or compliance teams.
It affects:
capital expenditure;
procurement;
technology strategy;
market entry;
financing;
intellectual property;
M&A;
manufacturing location.
Boards should therefore incorporate geopolitical scenarios into strategic planning.
4. Develop Regulatory Intelligence
Companies need continuous visibility into export controls, sanctions, tariff changes, investment restrictions and technology regulations.
The relevant question is not simply what the law says today.
It is where policy is moving.
5. Diversify Without Overreacting
The objective should not be to eliminate every Chinese or US dependency.
That would often be commercially unrealistic.
Instead, companies should identify dependencies where substitution is genuinely necessary and maintain commercial relationships where the risks remain manageable.
This is the emerging logic of selective de-risking.
Executive Outlook
The US-China rivalry is entering a new phase.
Tariffs remain important, but they increasingly function as one component of a much broader economic-security strategy.
The deeper contest is over who controls the infrastructure that makes modern economic activity possible.
Semiconductors determine access to advanced computing.
AI determines control over a growing layer of knowledge and productivity.
Rare earths influence advanced manufacturing.
Financial infrastructure determines how capital moves.
Sanctions determine who can access parts of the global financial system.
Technology standards determine how future systems interact.
Industrial policy determines where strategic production capacity is built.
Together, these elements form something larger than a trade dispute.
They form a contest over economic architecture.
The United States retains enormous advantages in finance, advanced technology, capital markets and alliances. China possesses extraordinary manufacturing scale, critical-mineral processing capabilities, industrial capacity and an increasingly sophisticated technology ecosystem. Neither side can easily remove its dependencies on the other without imposing significant economic costs on itself.
That creates the central paradox of the new rivalry.
The more strategically important the relationship becomes, the harder complete separation becomes.
For corporations, this means geopolitical risk can no longer be treated as an external variable.
It is becoming part of the economics of doing business.
For emerging markets, the contest creates a more complicated environment—but potentially a significant opportunity. Countries able to provide trusted infrastructure, strategic resources, competitive manufacturing and political flexibility may become increasingly valuable to companies seeking alternatives to concentrated supply chains.
The critical question for the global economy is therefore no longer simply whether the US and China will trade with one another.
They almost certainly will.
The more consequential question is which side, and which network of partners, will control the critical infrastructure on which the next generation of global commerce depends.
That is the contest now unfolding.
And for businesses, investors and governments, understanding where those points of control are emerging may matter more than understanding the next tariff announcement.
