China's recent breakthroughs in lithography technology are ratcheting up pressure on ASML, the Dutch semiconductor equipment giant, and could undermine the effectiveness of Western export controls on chip-making machinery. The developments, which come amid escalating US-China tensions over advanced technology, may reshape the global supply of semiconductors and complicate trade negotiations between the two countries.
What the advances mean for ASML
ASML is the world's sole supplier of extreme ultraviolet (EUV) lithography systems, essential for producing the most advanced chips. The company has been barred from selling its top-tier machines to Chinese customers under US-led export restrictions. But if China can now produce its own competitive lithography gear, ASML's market dominance and the rationale for those controls could be undermined. The Dutch firm has already seen some impact: its sales to China have dropped, and it faces growing competition from domestic Chinese manufacturers.
Export controls under threat
Western governments, particularly the United States, have relied on export controls to slow China's semiconductor ambitions. The logic is that by denying China access to cutting-edge equipment, they can keep the country dependent on foreign technology. But China's lithography advancements suggest that these controls may be losing their bite. If Chinese companies can develop their own advanced lithography systems, the restrictions become less meaningful, and the US may need to rethink its strategy.
Shifting chip supply dynamics
The global chip supply chain has long been dominated by a few key players: Taiwan's TSMC, South Korea's Samsung, and ASML in the Netherlands. China's progress in lithography could allow it to produce more advanced chips domestically, reducing its reliance on imports and potentially flooding the market with lower-cost alternatives. That would alter the balance of power in the semiconductor industry and could lead to new trade frictions.
Impact on US-China trade talks
Technology has been a central flashpoint in US-China trade negotiations. The Biden administration has maintained strict export controls on chip equipment, while China has pushed back with its own industrial policies. China's lithography advances could give Beijing more leverage in future talks, as it may no longer need to rely on Western suppliers for critical technology. The next round of trade discussions, expected later this year, will likely see chip technology at the top of the agenda.
For now, ASML is watching closely. The company has not commented publicly on the latest Chinese developments, but its investors are already pricing in the risk. The question hanging over the industry is whether China's progress is sustainable — and how quickly the West will respond.
