HIROSHIMA, Japan (AP) — The Group of Seven advanced economies are expected to announce a new set of sanctions against Russia to try to further hinder its war effort in Ukraine during their summit in Hiroshima, Japan. In traveling to Japan, Ukrainian President Volodymyr Zelenskyy will help to drive home the need to better enforce measures meant to stifle Moscow’s war machine. Russia is now the most-sanctioned country in the world, but there are questions about their effectiveness. EU Council President Charles Michel said the plan was to close loopholes and ensure the sanctions are painful for Russia, not for the countries enforcing them.
