The tech war between the United States and China has escalated to unprecedented levels, with semiconductors at the heart of the conflict. The U.S. views China’s advances in chip technology as a direct threat to its technological and military supremacy. To counter this, Washington has imposed sweeping sanctions targeting Chinese tech giants like Huawei and SMIC, effectively cutting them off from access to advanced semiconductor technology.
Recent reports indicate that the U.S. has pressured Taiwan’s TSMC, the world’s leading semiconductor foundry, to halt the supply of 7nm and smaller chips to Chinese firms. This move further isolates China from critical technologies needed for AI, 5G, and advanced computing, but it also disrupts global supply chains, leaving companies in South Korea and beyond grappling with uncertainty.
The U.S. has doubled down on its semiconductor strategy with the CHIPS and Science Act, allocating $52.7 billion to boost domestic chip manufacturing and R&D. While this presents opportunities for South Korean firms like Samsung and SK Hynix to expand their presence in the U.S., it also comes with risks. The potential rollback of subsidies under a new Trump administration has already sent ripples of concern through the industry, highlighting the precarious nature of investing heavily in the U.S.
Japan’s Comeback
Once a dominant force in the semiconductor industry, Japan is determined to reclaim its lost glory. With government-backed initiatives amounting to $67 billion, Japan is leveraging partnerships with global players like TSMC and IBM to rebuild its semiconductor ecosystem. The establishment of the JASM (Japan Advanced Semiconductor Manufacturing) fab in Kumamoto Prefecture marks a significant milestone in Japan’s resurgence, symbolizing its strategic alliance with Taiwan.
Japan’s ambitions extend beyond rebuilding its industry; they are rooted in a broader vision of securing technological and economic sovereignty. By prioritizing advanced packaging technologies and cutting-edge processes like 2nm nodes, Japan is positioning itself as a critical player in the next wave of semiconductor innovation.

Spurred by U.S. sanctions, Beijing has poured astronomical sums into its chip industry through state-backed programs like “Made in China 2025” and its 14th Five-Year Plan. While China’s advanced chip production capabilities lag years behind global leaders, it has made significant progress in legacy semiconductors, which still account for the majority of global demand.
China’s focus on legacy chips—28nm and older nodes—serves a dual purpose. These chips are critical for industries like automotive, consumer electronics, and industrial manufacturing, where cutting-edge technology is not always necessary. By cornering this market, China aims to wield influence over global supply chains while buying time to catch up in advanced nodes. South Korea, heavily reliant on both advanced and legacy semiconductors, must prepare for increased competition from a more self-sufficient China.
Taiwan’s Continued Dominance
In this high-stakes race, Taiwan’s TSMC remains the undisputed leader. The company controls over 50% of the global foundry market, dominating advanced nodes such as 5nm, 3nm, and soon-to-be 2nm technologies. TSMC’s role as a key supplier to global tech giants like Apple, Nvidia, and AMD solidifies its position as a linchpin in the semiconductor ecosystem.
For South Korea, Taiwan’s dominance is a constant source of pressure. While Samsung Electronics has made significant strides in the foundry market, its 16% share pales in comparison to TSMC’s. The gap is widening as TSMC continues to attract high-value contracts and reinvest in cutting-edge R&D. This dynamic raises critical questions for South Korea: Can it compete with TSMC in the advanced foundry space, or should it focus on other niches where it can differentiate itself?
The global semiconductor race is both an opportunity and a challenge for South Korea. The U.S.-China rivalry, Japan’s resurgence, China’s push for self-reliance, and Taiwan’s continued dominance create a complex and volatile environment. For South Korea, the stakes are existential. To remain competitive, the nation must navigate these dynamics carefully, leveraging its strengths while addressing its vulnerabilities.
