TOKYO (AP) — Japan has formally approved additional sanctions against Russia over the unrest in Ukraine.

Chief Cabinet Secretary Yoshihide Suga said Tuesday the sanctions include the freezing of assets held in Japan by 40 individuals and two groups supporting the separation of Crimea from Ukraine, and a ban on Crimean imports. He said the steps are in line with measures taken by European Union and Group of Seven nations.

Japan introduced the plans last week after the downing of Malaysia Airlines Flight 17.

The U.S. and Ukraine accuse pro-Russia rebels of firing a missile that brought the plane down, killing all 298 people on board.

Washington and EU have debated imposing tougher sanctions against Moscow over its support for the rebels. Japan has been modest on sanctions against Russia.
