Leaders of the world’s most developed nations will hold video conversations with Ukrainian President Volodymyr Zelenskyy on Sunday, according to a spokesperson for Germany’s acting G7 chair.

“The German chancellor [Olaf Scholz] will hold his third video conference with his G7 colleagues since the beginning of the year,” Christiane Hoffmann said on Friday, stressing that May 8 is a “historic occasion marking the end of World War II in Europe.”

“It will cover current issues, particularly the situation in Ukraine. Ukrainian President Zelenskyy will take part and report on the current situation in his country.”

US President Joe Biden on Wednesday said he was “open” to imposing more sanctions on Russia and would be discussing measures with allies from the G7 in the next few days.

“We’re always open to additional sanctions,” Biden said shortly after the European Union announced plans for banning Russian oil imports and other new measures punishing Moscow for its invasion of Ukraine.

“I’ll be speaking to members of the G7 this week about what we’re going to do or not,” Biden told reporters.

Canada, France, Germany, Italy, Japan, Britain and the United States comprise the Group of Seven club of rich nations.
