South China Morning Post examines whether Beijing's tightened export controls on tungsten — a critical material for chip interconnects, wire bonding and advanced packaging — could disrupt Japan's AI semiconductor supply chain. The piece frames tungsten as a potential pressure point for Japanese chipmakers and packaging suppliers reliant on Chinese mineral exports, with knock-on risks for downstream AI chip assembly.
Why it matters: Sector-wide supply chain risk story on China's critical minerals leverage affecting AI chip packaging materials; relevant to global semi but no specific new policy action or named-company impact on tracked KR/TW names.
