Geopolitical competition has turned the semiconductor industry into a key sector being contested globally. As a US-China technology dispute continues to heat up, Washington is implementing a “small yard and high wall” technology control strategy in an attempt to slow China’s development of semiconductors, and to prevent high-end artificial intelligence (AI) chips from being used for Chinese military purposes. On the other hand, Beijing is trying to break through that wall, using talent mobility and AI as shortcuts.
China’s semiconductor industry faces four major bottlenecks: semiconductor equipment for advanced manufacturing processes, electronic design automation (EDA) software for semiconductor design, high-end AI chips and semiconductor talent.
In particular, the US’ restriction on exports of extreme ultraviolet equipment has made it more difficult for China to obtain technology more advanced than the 7-nanometer manufacturing process, which has become a key factor in constraining its development.
By adopting the technology of optical proximity correction, China has attempted to improve the low yield rate of deep ultraviolet multiple exposure processes caused by the optical proximity effect. It has also utilized AI to enhance the accuracy and efficiency of optical proximity correction in an attempt to break through the technological bottleneck and the US blockade.
The US “small yard and high wall” blockade focuses on the extreme ultraviolet equipment and deep ultraviolet lithography equipment, as well as high-end AI chips and EDA software.
It also prohibits US citizens from assisting China in the development of high-end chips. China has responded to the US controls in a roundabout way, through pre-stocking, shell companies and even smuggling.
Chinese start-up SEIDA has made significant progress in optical proximity correction through the transfer of core EDA talent from Siemens, demonstrating that in the face of US bans, the outflow of talent would result in a spillover of technology to China.
Taiwan must be careful in its response to this situation to ensure that it can maintain a leading position in the complex US-China-Taiwan “silicon triangle.”
The government should not only develop a list of national core and critical technologies to bolster its mastery of semiconductor technology, but also cooperate with international allies in a multilateral export control system to prevent the outflow of advanced chip technology to China, as well as the illegal transfer or mobility of key semiconductor equipment, technology and talent, to protect core technologies and outstanding semiconductor talent.
Recently, the EU has pushed for “de-risking” its economy from China and strengthening export controls to prevent sensitive dual-use technologies from being leaked to China through overseas investments. Meanwhile, Taiwan should enhance the cultivation and retention of semiconductor talent, bolster independent innovation in IC design and continue to develop emerging semiconductor technologies such as silicon photonics, small chip packaging and AI applications, to ensure the competitiveness of Taiwan’s semiconductor industry, and to push the industry to new peaks.

In the US’ National Security Strategy (NSS) report released last month, US President Donald Trump offered his interpretation of the Monroe Doctrine. The “Trump Corollary,” presented on page 15, is a distinctly aggressive rebranding of the more than 200-year-old foreign policy position. Beyond reasserting the sovereignty of the western hemisphere against foreign intervention, the document centers on energy and strategic assets, and attempts to redraw the map of the geopolitical landscape more broadly. It is clear that Trump no longer sees the western hemisphere as a peaceful backyard, but rather as the frontier of a new Cold War. In particular,
When it became clear that the world was entering a new era with a radical change in the US’ global stance in US President Donald Trump’s second term, many in Taiwan were concerned about what this meant for the nation’s defense against China. Instability and disruption are dangerous. Chaos introduces unknowns. There was a sense that the Chinese Nationalist Party (KMT) might have a point with its tendency not to trust the US. The world order is certainly changing, but concerns about the implications for Taiwan of this disruption left many blind to how the same forces might also weaken
As the Chinese People’s Liberation Army (PLA) races toward its 2027 modernization goals, most analysts fixate on ship counts, missile ranges and artificial intelligence. Those metrics matter — but they obscure a deeper vulnerability. The true future of the PLA, and by extension Taiwan’s security, might hinge less on hardware than on whether the Chinese Communist Party (CCP) can preserve ideological loyalty inside its own armed forces. Iran’s 1979 revolution demonstrated how even a technologically advanced military can collapse when the social environment surrounding it shifts. That lesson has renewed relevance as fresh unrest shakes Iran today — and it should
As the new year dawns, Taiwan faces a range of external uncertainties that could impact the safety and prosperity of its people and reverberate in its politics. Here are a few key questions that could spill over into Taiwan in the year ahead. WILL THE AI BUBBLE POP? The global AI boom supported Taiwan’s significant economic expansion in 2025. Taiwan’s economy grew over 7 percent and set records for exports, imports, and trade surplus. There is a brewing debate among investors about whether the AI boom will carry forward into 2026. Skeptics warn that AI-led global equity markets are overvalued and overleveraged
