MOSCOW—President Donald Trump told Russian President Vladimir Putin in a phone call on June 1 about his idea of holding an expanded Group of Seven summit later this year with a possible invitation for Russia, the Kremlin and the White House said.

Trump said on May 30 he would postpone a G-7 summit he had hoped to host next month until September or later and expand the list of invitees to include Australia, Russia, South Korea and India.

A White House statement on the call said Trump and Putin discussed “progress towards convening the G7.”

Britain and Canada have since spoken out against the idea of readmitting Russia to a forum it was expelled from in 2014 after annexing the Crimea region from Ukraine.

Russia had said earlier on June 1 that it was looking for more details before responding.

The two leaders also discussed the OPEC+ deal on oil output cuts, and measures to fight the coronavirus, the Kremlin said. Putin thanked Trump for a delivery of U.S. ventilators, the Kremlin said, and congratulated Trump on the first spaceflight of NASA astronauts from U.S. soil in nine years.

Trump and Putin also discussed “the need for effective arms control,” the White House said.
