TOKYO/SEOUL -- The Japanese government on Monday announced it will tighten restrictions on exports of semiconductor manufacturing materials to South Korea, in a move that could hinder Asian supply chains.
Japan's trade ministry said the decision came in response to what it deemed the "occurrence of an inappropriate matter." But the ministry did not clarify what that means, and the restrictions at least appear to be a reaction to Seoul's stance on a dispute over compensation for wartime labor. This could leave Japan vulnerable to accusations that it is abusing international trade rules.
