Potential Breach of Export Restrictions: ASML’s Advanced Chip Machine Allegedly in China
In a significant development in the ongoing global semiconductor cold war, U.S. Commerce Secretary Howard Lutnick has raised concerns with Dutch chip-equipment giant ASML. The issue at hand is the alleged illegal transfer of one of ASML’s top-tier Extreme Ultraviolet (EUV) lithography machines — the world’s most advanced chipmaking tool — to China. This move, if true, would be in violation of U.S.-led export restrictions. The warning was issued during a series of high-level meetings between Lutnick and ASML’s senior leadership, as first reported by Bloomberg on June 18, 2026.
ASML has categorically denied these allegations, asserting that it has never shipped an EUV machine to China. Furthermore, the company claims to know the exact location of every EUV tool it has ever built. The company has labelled these rumors as “inaccurate and damaging” to its reputation. As of June 19, 2026, no public evidence has been presented to confirm any transfer.
The implications of this situation are colossal. EUV machines are the critical bottleneck for producing the most advanced semiconductors below the 7nm node — the chips powering cutting-edge AI models and high-performance computing clusters. ASML holds a global monopoly on EUV technology, and these machines have historically only been sold to U.S.-allied chipmakers such as TSMC, Intel, and Samsung. The fact that China accounted for roughly a third of ASML’s 2025 revenue adds further financial complexity to this geopolitical standoff.
This incident could potentially trigger tighter export controls, impact ASML’s revenue, and accelerate China’s push to develop domestic chipmaking alternatives. This could reshape the global AI chip supply chain.
