Taiwan joined a yearslong US campaign to curtail China’s technological ascent when it blacklisted the country’s AI and chipmaking champions, an unprecedented step that may signal a resurgent effort to isolate its powerful neighbor’s semiconductor sector.

Taiwan has added China's Huawei and SMIC to its trade blacklist in a move that further aligns it with U.S. trade policy and comes amid tensions with Beijing.

Chinese companies Huawei and SMIC may have a difficult time accessing resources needed to build AI chips, due to Taiwanese export controls.
