Tech standoff widens
The U.S.-China economic dispute is escalating from tariffs into technology: China publicly denounced a U.S. move as sabotaging scientific exchanges, while a U.S. bill would block exports of all semiconductor-equipment — including DUV and etching tools — to China. That matters because cutting off the machines and research links that undergird chip production targets China’s industrial upgrading and could harden structural rivalry, an outcome U.S. trade officials say would be complicated further if China deepens ties with Iran.

China and the United States are now fighting over the machines that make chips, not just the chips themselves. On April 10, China’s foreign ministry said a U.S. move was sabotaging normal scientific and technological exchanges between the two countries. (english.news.cn) At almost the same time, U.S. lawmakers were pushing a bill that would stop exports to China of older deep ultraviolet tools, not just the most advanced extreme ultraviolet machines already under heavy restriction. The proposal also reaches equipment used across ordinary chip production lines, including etching tools. (chosun.com, nbcnews.com) Deep ultraviolet lithography is the step that draws tiny circuit patterns onto silicon wafers, like projecting a stencil onto film. China has struggled to get the very newest version of that machinery, so older deep ultraviolet systems still matter because they can make a huge share of the chips used in cars, appliances, power gear, and industrial electronics. (chosun.com, bloomberg.com) Etching tools do the opposite job: instead of drawing patterns, they carve those patterns into the wafer layer by layer, like using acid and masks to cut grooves into metal. If a factory loses access to both lithography and etching gear, it is not just slowed at the frontier; even mature production becomes harder to expand. (chosun.com, nbcnews.com) That is why this fight looks different from the earlier export controls that focused on the most advanced chips for artificial intelligence. The new push goes after the factory floor itself, which is the bottleneck that decides how many chips China can make at home in five years, not just what it can buy this quarter. (chosun.com, bloomberg.com) Beijing’s complaint about scientific exchanges points to the other half of the contest. Chip industries are built not only with machines from companies like ASML, Applied Materials, and Lam Research, but also with university labs, visiting researchers, joint papers, and training pipelines that move know-how across borders. (english.news.cn, chosun.com) Washington has been tightening that choke point for years. Chosun reports that since 2019 the United States has progressively blocked advanced semiconductor technology and manufacturing equipment exports to China, starting with measures tied to Huawei and later widening through pressure on allies such as Japan and the Netherlands. (chosun.com, chosun.com) The immediate result is not that China stops making chips tomorrow. The more likely result is a slower, more expensive climb, because domestic toolmakers have to replace imported systems one category at a time while Chinese factories keep running huge volumes of less advanced output. (chosun.com, chosun.com) A second result is that allies get pulled deeper into the same fight. Bloomberg reported that the U.S. legislation is aimed not only at American firms but also at tool sales involving the Netherlands and Japan, because a ban works only if the countries that dominate chip gear move together. (bloomberg.com, chosun.com) Then there is the geopolitical layer. On April 10, U.S. Trade Representative Jamieson Greer said that if China gets involved with Iran, it would complicate matters, linking the trade relationship to a wider security map that now stretches well beyond tariffs and customs duties. (deccanherald.com) Put together, the message from both capitals is that the old argument over import taxes has turned into a contest over the wiring of the modern economy. One side is trying to deny the tools, the other is warning that even the classrooms and labs are becoming part of the blockade. (english.news.cn, chosun.com, deccanherald.com)
