Prime Minister Shinzo Abe has decided to visit Moscow in May to attend a ceremony marking the 75th anniversary of Russia's victory over Germany in World War II and to hold talks with President Vladimir Putin, a Japanese government source said Friday.

Japan and Russia are trying to arrange a meeting between Abe and Putin on May 8 or May 10, according to the source. The ceremony will be held on May 9.

"He is invited to the ceremony. There is no reason to turn it down," the source said.
