ASML is facing pressure from both sides of the US-China technology divide. US restrictions on high-end chip equipment exports threaten the Dutch group's access to a major market, while China's drive to build its own semiconductor supply chain could gradually reduce dependence on foreign suppliers.

That tension is drawing renewed attention after China unveiled a homegrown advanced lithography machine. The development highlights Beijing's push for technological independence in chip production, an area where ASML has long held a crucial position because its tools are central to making advanced semiconductors.

For ASML, China has been an important source of demand, but tighter export rules can limit what the company is able to sell there. At the same time, if Chinese firms improve local alternatives, ASML could eventually face stronger competition inside a market that has been strategically important for future growth.

The situation shows how geopolitics and industrial policy are reshaping the chip equipment business. ASML remains a key global supplier, but the combination of US curbs and China's domestic technology push is creating a more complicated outlook for the company in one of the world's most important semiconductor markets.
