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.

The move will further tighten existing loopholes and curb collaboration between Chinese firms on the entity list and Taiwanese tech leaders.
