China: tariff and chip pressure
The White House warned China could face a 50% tariff if it’s found supplying weapons to Iran, signalling a trade penalty tied to Middle East activity. ( ). At the same time, U.S. lawmakers are moving to ban exports of a critical ASML tool that China’s chip industry depends on, targeting upstream manufacturing capability. (wccftech.com). Yet global semiconductor-equipment sales hit a record US$135 billion as AI drove capital investment, producing a mismatch between surging demand and tightening export controls. (digitimes.com)
President Donald Trump has opened a new front in pressure on China, threatening a 50% tariff if Beijing is found supplying weapons to Iran. (cnbc.com) Trump posted the warning on April 8, saying “any and all” goods from countries arming Iran would be hit “immediately” and with “no exclusions or exemptions.” Reuters reported the threat came hours after he agreed to a two-week ceasefire with Tehran. (cnbc.com, usnews.com) On April 12, Trump said the same penalty would apply to China if U.S. officials “catch them” sending military equipment to Iran, according to reports of his Fox News interview. Politico said the legal path for such a tariff is unclear. (telegraph.co.uk, politico.com) At the same time, lawmakers in Washington are trying to tighten the screws on China’s chip industry. A bipartisan bill introduced on April 2 would restrict more semiconductor-manufacturing tools sold by foreign companies, including ASML of the Netherlands and Tokyo Electron of Japan. (bloomberg.com, usnews.com) Those tools are the factory machines used to print and shape circuits on silicon wafers. Reuters said the proposed law, called the MATCH Act, is designed to stop Chinese companies from getting equipment they cannot yet make themselves and to put foreign suppliers under rules closer to those already faced by U.S. firms. (usnews.com) ASML is already exposed. CNBC reported on April 7 that its shares fell after the proposal, and that further curbs could damage a China business that had already been shrinking under earlier export controls. (cnbc.com) The squeeze is landing as chip-equipment spending is still climbing. SEMI, the industry trade group, said worldwide semiconductor-equipment sales rose 15% to $135.1 billion in 2025 from $117.1 billion in 2024, driven by investment in advanced logic, memory and artificial-intelligence capacity. (semi.org) That leaves China facing two different risks at once: a tariff threat tied to Middle East arms flows and a technology squeeze aimed at the machines behind chip production. One pressure point is geopolitical; the other sits deep inside the supply chain. (cnbc.com, usnews.com)) What happens next depends on two separate tests: whether Washington produces evidence of Chinese arms shipments to Iran, and whether the MATCH Act or similar export controls become law. For now, the message from Washington is that trade penalties and chip controls are being used in the same contest. (politico.com, bloomberg.com)
