Russia threatens proportionate countermeasures against Japan's 27th sanctions package

Japan's 27th sanctions package expands restrictions on Russian entities to include shadow fleet shipping for the first time, directly affecting energy transport infrastructure and circumvention mechanisms. Russia's announcement of proportionate countermeasures creates uncertainty around bilateral trade, investment, and potential sectoral retaliation targeting Japanese companies or interests in Russia. The timing and scope of Russian response measures remain unspecified, creating operational risk for Japanese exporters, investors, and supply chain participants with Russian exposure.
