Is China using its critical supply chain dominance as diplomatic leverage?
Core argument: China's commerce ministry said it would freeze exports of "dual-use" materials, which have both civilian and military applications, to 20 Japanese companies, while adding another 20 groups to a new "watch list".
China has restricted exports of rare earth magnets and other critical materials to dozens of leading Japanese companies in an escalation of a dispute with Tokyo. China’s commerce ministry on Tuesday said it would freeze the flow of “dual-use” materials, which have applications to both civilian and military industries, to 20 Japanese companies. Another 20 groups are being added to a new “watch list”. The restrictions deepen a row with Japan and illustrate how Beijing is wielding its dominance in critical supply chains to exert diplomatic pressure. The global automotive industry is heavily dependent on China for rare-earth magnets. The announcement hit Japanese share prices, with MHI falling as much as 3%, Kawasaki Heavy shedding 4%, IHI Group losing 5.7% and NEC dropping more than 6%. Subaru fell 3.5%.
