The Great Tech War: How U.S. Suppression of Foreign Companies is Reshaping the World

In the 1980s, Japan’s Toshiba and Hitachi were  rising stars in the global semiconductor industry, outcompeting American giants with cutting-edge technology. Fast forward to today, and we see a similar pattern playing out with companies like Huawei, TikTok, ASML, and TSMC. These companies, hailing from China, Singapore, the Netherlands, and Taiwan, have all faced significant pressure from the United States. But why is the U.S. targeting these foreign firms, and what does it mean for the future of global technology, economics, and geopolitics? Let’s dive into the story.

The Rise of Competitors and the U.S. Response

The U.S. has long been the dominant force in technology and innovation, but its position is increasingly challenged by foreign competitors. In the 1980s, Japan’s semiconductor industry, led by companies like Hitachi and Toshiba, threatened U.S. dominance. The U.S. responded with tariffs, anti-dumping measures, and the 1986 U.S.-Japan Semiconductor Trade Agreement, which forced Japan to limit exports and open its markets to U.S. firms. While the U.S. regained its lead, Japan’s experience taught the world a valuable lesson: over-reliance on a single market can be risky.

Fast forward to the 21st century, and China’s Huawei emerged as a global leader in 5G technology. The U.S. saw Huawei as a national security threat, fearing its equipment could be used for espionage by the Chinese government. The U.S. imposed export controls, banned Huawei from accessing critical American technologies, and pressured allies to exclude Huawei from their 5G networks. This move not only crippled Huawei’s global ambitions but also accelerated China’s push for technological self-reliance.

Similarly, TikTok, the wildly popular social media app owned by China-based ByteDance, faced scrutiny in the U.S. over concerns about data privacy and Chinese influence. The Trump administration attempted to ban TikTok or force its sale to a U.S. company. While the ban was not fully implemented, the case highlighted the growing importance of data sovereignty and the geopolitical risks of foreign-controlled platforms.

The Semiconductor Wars: ASML, NVIDIA, and TSMC

The semiconductor industry has become the epicenter of the U.S.-China tech rivalry. Semiconductors are the lifeblood of modern technology, powering everything from smartphones to military systems. Three companies—ASML, NVIDIA, and TSMC—have found themselves at the heart of this conflict.

ASML, a Dutch company, is the world’s only manufacturer of extreme ultraviolet (EUV) lithography machines, which are essential for producing advanced semiconductors. The U.S. has pressured the Netherlands to restrict ASML from selling its most advanced machines to China, fearing they could boost China’s semiconductor industry and military capabilities. This case underscores the importance of controlling critical technologies and the vulnerabilities of global supply chains.

NVIDIA, a U.S. company and a leader in AI chips, has also been caught in the crossfire. The U.S. government imposed export controls on NVIDIA’s high-end AI chips to prevent their use in China’s military and AI development. While these restrictions protect U.S. national security, they also hurt NVIDIA’s revenues, as China is a major market for AI chips. NVIDIA’s response? Developing downgraded versions of its chips to comply with U.S. regulations while maintaining some access to the Chinese market.

Then there’s TSMC, the Taiwanese semiconductor giant that produces over 90% of the world’s most advanced chips. TSMC’s dominance has made Taiwan a focal point of U.S.-China competition. The U.S. has encouraged TSMC to build fabrication plants in America to reduce reliance on Taiwan, while also imposing export controls to limit China’s access to advanced chipmaking technologies. TSMC’s story highlights the geopolitical risks of concentration and the urgent need for supply chain diversification.

Lessons from the Great Tech War

These cases offer several key lessons about the evolving dynamics of global technology and geopolitics:

National Security Trumps Globalization: The U.S. has prioritized national security over free trade, using export controls, sanctions, and regulatory measures to restrict foreign competitors. While this protects U.S. interests, it risks fragmenting the global economy and undermining the benefits of globalization.

Technological Decoupling: The U.S.-China tech rivalry has led to a decoupling of the two largest economies, creating parallel technology ecosystems. This bifurcation could lead to inefficiencies, higher costs, and slower innovation.

Economic Statecraft as a Geopolitical Tool: The U.S. has demonstrated its ability to use economic tools—such as export controls and extraterritorial legal enforcement—to achieve geopolitical goals. While effective, this approach risks alienating allies and encouraging other countries to develop similar tools.

Resilience and Self-Reliance: The restrictions on companies like Huawei, ASML, and TSMC have underscored the importance of resilience and self-reliance in critical industries. Countries and companies are now investing heavily in domestic capabilities to reduce dependence on foreign technologies.

China’s Push for Self-Sufficiency: U.S. restrictions have accelerated China’s push for technological self-reliance, leading to massive investments in semiconductors, AI, and other critical sectors. If China succeeds, the global balance of power could shift.

The Future of Global Technology and Geopolitics

The U.S. suppression of foreign companies reflects a broader trend toward economic nationalism and technological rivalry in an increasingly multipolar world. While these actions protect U.S. interests in the short term, they also carry significant risks, including economic fragmentation, reduced innovation, and strained alliances.

For the global community, the challenge will be to navigate this new reality while preserving the benefits of globalization and cooperation. This will require:

Balancing National Security and Economic Interdependence: Countries must find ways to protect their strategic interests without undermining global collaboration.

Investing in Resilience and Innovation: Diversifying supply chains, investing in domestic capabilities, and fostering innovation will be critical to reducing vulnerabilities.

Strengthening Multilateral Frameworks: Reforming and strengthening international institutions and rules can help manage competition and prevent conflicts.

Promoting Ethical Leadership: The U.S. and other major powers must lead by example, demonstrating a commitment to fairness, transparency, and the rule of law.

Conclusion: A New World Order

The incidents involving Hitachi, Huawei, TikTok, ASML, NVIDIA, and TSMC are not just isolated cases but part of a broader transformation in the global order. As technology becomes increasingly central to economic and geopolitical power, the competition between the U.S. and China will shape the future of the world.

For companies, the ability to adapt to geopolitical pressures will be a key determinant of success. For countries, the challenge will be to balance national security with economic interdependence. And for the global community, the goal must be to build a more resilient, equitable, and collaborative world.

The Great Tech War is far from over, and its outcome will define the 21st century. As we navigate this new reality, one thing is clear: the stakes have never been higher.
