Evolving U.S.-China Tech and AI Export Policies Amid Global Competition and Fragmentation

The global technology landscape is undergoing a profound transformation driven by geopolitical rivalry, legal reforms, and regional regulatory divergence. As the United States recalibrates its approach to export controls and strategic engagement with China, recent developments reveal a nuanced strategy aimed at maintaining technological leadership, supply chain resilience, and national security—while avoiding the pitfalls of full decoupling. Simultaneously, China accelerates its efforts toward self-sufficiency, intensifying a race that risks fragmenting the global innovation ecosystem.

Strategic Recalibration in U.S.-China Tech Rivalry

The Biden administration has shifted from broad bans to targeted, selective export approvals. A prime example is the Nvidia H200 AI chips, which received export clearance to China, signaling a strategic compromise. This move reflects an effort to support US influence in high-end AI hardware while mitigating security concerns associated with comprehensive restrictions. By allowing controlled exports, the U.S. aims to balance innovation support with security—a marked departure from the more rigid policies of previous administrations.

In tandem, domestic semiconductor manufacturing is receiving substantial investment. Companies like TSMC are building new fabs in Arizona, part of a broader initiative to domesticate the semiconductor supply chain. These efforts are designed to reduce reliance on Chinese manufacturing, bolster supply chain resilience, and foster technological autonomy—key components of the U.S. strategy to counter China’s rapid push for self-sufficiency.

However, progress faces hurdles. The US is actively seeking to expand domestic sources of critical minerals and rare earth elements, essential for semiconductors and AI hardware. Yet, logistical delays and environmental concerns have slowed these efforts, exposing vulnerabilities in vital supply chains.

On the corporate front, firms like TikTok are establishing U.S.-based joint ventures and local operations to maintain market access amid mounting regulatory pressures. While operationally complex, such adaptations are seen as necessary for sustainability under an increasingly restrictive environment.

Implication: These measures demonstrate a deliberate, calibrated strategy—aiming to strengthen supply chains and technological competitiveness without severing economic ties, thus avoiding full decoupling that could stifle innovation and economic growth.

Legal and Political Shifts Reshaping Trade Policy

Recent legal rulings and legislative initiatives are reshaping the scope and flexibility of U.S. export controls:

• The Supreme Court limited the president’s authority to impose broad tariffs via executive orders, ruling that such measures require congressional approval. This decision curtails executive flexibility, pushing policymakers toward more legislative-driven trade strategies.

• As a consequence, the U.S. paused certain tariff collections, acknowledging the legal limitations on unilateral executive actions. Experts interpret this shift as a move away from the aggressive tariff policies of the Trump era, signaling a more restrained approach.

• Meanwhile, Congress is advancing bills to tighten export controls on semiconductors and AI technologies:

  • Ending the ‘first sale’ valuation practice, which undervalues shipments for duty purposes, aiming to increase tariffs and support domestic manufacturing.
  • The USMCA review by the U.S. International Trade Commission seeks to reshape regional supply chains and tighten export restrictions, affecting North American cooperation.

• Partisan debates continue, with Donald Trump advocating for higher tariffs (up to 15%) and criticizing recent legal restrictions as ‘anti-American’. Conversely, bipartisan efforts focus on reducing tariffs on Canadian imports and fostering regional economic integration.

Significance: The legal landscape is becoming more constrained, prompting the U.S. to adjust its trade toolbox, which could delay or complicate future export controls and trade policies amid ongoing legal and political uncertainties.

Industry and China’s Countermeasures

Major corporations are adapting swiftly to these shifting geopolitical and regulatory environments:

• Supply Chain Localization: TSMC’s Arizona fabs exemplify efforts to diversify semiconductor supply chains, reducing dependence on Chinese manufacturing and building resilient, domestically anchored ecosystems.

• Corporate Restructuring: Companies like TikTok are establishing U.S.-based joint ventures and local operations to maintain market access and navigate regulatory challenges. These operational shifts, although complex, are deemed essential for long-term sustainability.

• China’s Accelerated Self-Reliance:

  • The Chinese government is drafting tighter regulations to limit foreign access to strategic technologies, including restrictions on imports of foreign chips like Nvidia’s H200.
  • China continues heavy investments in semiconductor and AI sectors, aiming for self-sufficiency and reducing external vulnerabilities.
  • New policies curtail foreign chip imports and restrict foreign acquisitions of critical assets, aligning with China’s long-term goal of technological independence.

Implication: These countermeasures intensify global competition for technological independence, fragmenting supply chains and accelerating the race toward self-sufficiency.

Fragmentation and Regional Regulatory Divergence

The proliferation of region-specific and subnational regulations is deepening fragmentation within the global tech ecosystem:

• Countries like South Korea are implementing AI ethics and startup support policies, while France has introduced regulations limiting social media use among minors.

• U.S. states such as Texas are banning government use of platforms like Shein and Alibaba to enhance data security and assert economic sovereignty.

Consequences: This divergence increases compliance costs, reduces interoperability, and hampers collaborative innovation. Diplomatic efforts are ongoing to develop harmonized standards, but regional divergences pose significant challenges to global cooperation.

New Developments: Security, AI Governance, and Strategic Leverage

A notable recent event underscores the growing influence of national security on AI regulation:

• Defense Secretary Pete Hegseth has set a Friday deadline for AI firm Anthropic to lift restrictions on military weaponization. He threatens to revoke Pentagon contracts if the company does not remove limitations on AI weapon applications.

• Implication: This heightens political pressure on AI firms to align with national security interests. The linkage of procurement and export controls could reshape corporate policies on AI development and deployment, raising concerns about the militarization of AI and export restrictions serving as strategic tools.

Market Impact and Lessons from Past Tariff Policies

The interplay of legal constraints, regulatory divergence, and geopolitical tensions is already impacting markets:

• The Supreme Court ruling and tariff pause have introduced uncertainty into financial markets and industry strategies.

• Historical lessons: The tariffs introduced during the Trump era backfired on U.S. consumers and exporters, leading to higher prices, retaliation from trading partners, and disrupted supply chains. These impacts highlight the risks of aggressive tariff policies that fail to consider broader economic repercussions.

Current Implication: Policymakers are increasingly aware that overly aggressive trade restrictions can damage economic growth and innovation, prompting a more cautious approach that emphasizes targeted controls and diplomatic engagement.

Outlook: Navigating a Fragmented but Secure Global Tech Ecosystem

The evolving landscape suggests a gradual shift toward regionalization and strategic decoupling. Diplomatic coordination and industry resilience will be crucial in mitigating fragmentation’s adverse effects:

• Developing harmonized standards could ease compliance burdens and foster interoperable innovation.

• Investing in domestic capabilities remains a priority for the U.S. and China, but mutual dependencies may persist in certain sectors.

• The balance between security, sovereignty, and openness will define future policies, determining whether the world can maintain leadership in AI and advanced technology amid increasing regional divergence.

In conclusion, this period marks a transitional phase—one characterized by competition, cautious cooperation, and strategic fragmentation. The choices made today will shape the global tech ecosystem for years to come, with the overarching challenge being to balance innovation with security and sovereignty in an increasingly complex geopolitical environment.
