The blacklist targets several Mitsubishi Group subsidiaries and the National Institute for Defense Studies. Beijing claims these measures are necessary to fulfill international non-proliferation obligations, though the timing underscores deepening friction between the two nations. Alongside the export ban, a secondary watch list now covers 20 additional firms operating within Japan’s drone and nuclear fuel sectors. Exports to these companies face rigorous scrutiny, with authorities pledging to block any shipments linked to military end-uses.

This aggressive trade policy follows earlier restrictions on critical minerals, which Beijing imposed against major Japanese firms earlier this year. Observers link the intensifying economic pressure to recent diplomatic discord, specifically criticisms regarding Taiwan voiced by Prime Minister Sanae Takaichi. By restricting access to dual-use components, China is effectively leveraging its supply chain dominance to penalize Japan’s defense-related industrial growth.
