A Taiwanese think tank says gaps between Taiwan's and Washington's tech blacklists are letting some Chinese firms slip through — a warning shot for chipmakers and a potential tightening ahead.

• Taiwan has closely copied the U.S. blacklist since 2022, but never went back to check older entries, leaving holes in its own rules.
• Chinese memory chipmaker Fujian Jinhua, blocked by the U.S. since 2018, is still absent from Taiwan's list — and is reported to act as a hidden factory for Huawei.
• Taiwanese companies selling to those unlisted firms break no end-user rules, and the government has no legal grounds to stop them.
• Most firms both sides did blacklist are Chinese or Russian, largely in electronics and tied to China's military buildup.
• The fix needs no new law — trade regulators can simply add the most important missing names, as they did in a big revision last year.

Outlook: Expect Taiwan to selectively add older Chinese tech names to its control list rather than adopt every U.S. designation wholesale.
