Congress Wants to Force US Allies to Choose: Sell Chip Equipment to China, or Sell to America
What happened
The House Foreign Affairs Committee advanced the MATCH Act on April 22 in what members called the largest markup on semiconductor export controls in congressional history. The bill would require the Netherlands (home of ASML, the sole supplier of extreme ultraviolet lithography machines) and Japan to align their chip equipment export restrictions with US rules within 150 days, or face US restrictions on selling to them. The bill also targets cryogenic etching tools that China cannot manufacture domestically. China's Commerce Ministry responded immediately, warning that the legislation would disrupt global semiconductor supply chains and threatening retaliation. House Foreign Affairs Chair Brian Mast is pushing to attach the bills to the National Defense Authorization Act to guarantee a floor vote.
The MATCH Act does not just restrict what the US sells to China. It coerces US allies into restricting what they sell to China, or face consequences. The Netherlands and Japan did not agree to this. They are being told to comply or be treated like adversaries by the country that is supposed to be their partner.
The Hidden Bet
Allied governments will comply with the 150-day ultimatum rather than face US secondary restrictions.
ASML generates roughly 30% of its revenue from China. The Dutch government cannot absorb that economic hit without domestic political consequences. Japan faces the same math with its chip equipment firms. The assumption that allies will sacrifice their own semiconductor industries for US strategic goals is untested and possibly wrong.
Restricting access to cryogenic etching tools and DUV lithography will meaningfully slow China's chip development timeline.
DeepSeek V4 just demonstrated that frontier AI can be built with existing Huawei chips at lower cost than US alternatives. If China can develop efficient AI without cutting-edge silicon, the strategic value of restricting equipment depends on a hardware dependency that may already be eroding.
The NDAA is the right vehicle for tech export policy because it guarantees a vote.
Attaching contested export control legislation to the defense budget is the same move China makes when it bundles unrelated demands into trade talks. It bypasses the deliberative process that would force Congress to actually reckon with the allied relationship costs.
The Real Disagreement
The real dispute is not about whether China should have access to advanced chip equipment. The real dispute is about who has sovereignty over that decision. The US says it has the right to tell Dutch and Japanese firms what they can sell globally because those sales affect American national security. The Netherlands and Japan say that is an extraterritorial assertion of American law over their companies, their trade relationships, and their foreign policy. Both positions have merit. The US is right that a globally fragmented enforcement regime is weaker than a coordinated one. The allies are right that being given 150 days to restructure their industries or face sanctions is not a partnership. The US has the leverage to win this argument. Winning it may cost more in allied trust than the chip controls are worth.
What No One Is Saying
Micron is lobbying for tighter equipment restrictions while simultaneously depending on TSMC in Taiwan for its most advanced chips. If allied compliance deteriorates and supply chains fragment, Micron's own supply chain breaks. The companies pushing hardest for these controls are among those most exposed to their consequences.
Who Pays
ASML and Dutch semiconductor equipment workers
150 days after MATCH Act passage, if enacted.
Forced exit from China market, which represents roughly 30% of ASML revenue. If the Netherlands complies, Dutch taxpayers and workers absorb the loss. If it refuses, it faces US secondary restrictions.
US chip equipment firms (Lam Research, Applied Materials, KLA)
Immediate loss of orders; medium-term structural market loss over 3-5 years.
Tighter domestic restrictions cut their Chinese customer base. China will accelerate domestic alternatives. US equipment makers lose not just China sales but the engineering feedback loop that comes from their best customers.
US-allied governments
Within the 150-day compliance window if the bill becomes law.
Forced to choose between economic harm from China market loss and diplomatic harm from defying a US ultimatum. Either path weakens the alliance structure the NDAA is nominally designed to protect.
Scenarios
Allies comply under duress, China doubles down on domestic
Netherlands and Japan align restrictions to avoid US secondary sanctions. ASML and Japanese equipment firms exit China. China accelerates its domestic equipment development program, now with a clear target to beat.
Signal Dutch and Japanese governments announce compliance within 120 days of MATCH Act enactment; ASML stock drops 15-20% on China revenue write-down.
Allies resist, bill stalls or is softened in NDAA negotiations
Dutch and Japanese diplomatic pushback causes Senate to strip or modify the ally-coercion provisions. MATCH Act passes in weakened form without the 150-day ultimatum. The underlying China restrictions remain but enforcement remains bilateral.
Signal Senate Armed Services Committee removes or delays the allied compliance provisions in NDAA markup.
China retaliates across supply chain
China restricts rare earth and critical mineral exports to US and allied chip manufacturers in response to MATCH Act. US chip supply chains face cost spikes. The trade war over chips becomes a trade war over everything chips need.
Signal China's Commerce Ministry announces export licensing requirements for gallium, germanium, or rare earths within 60 days of MATCH Act committee vote.
What Would Change This
If China publicly demonstrates a domestically produced DUV lithography machine at scale — something it has been attempting for years — the entire premise of equipment controls collapses. The restrictions would then be slowing China's development by months, not years, and the allied relationship costs would clearly exceed the strategic benefit.
