BERLIN - The Group of Seven has agreed to reject Russia's demand to pay gas deliveries in rubles, said German Vice-Chancellor Robert Habeck on Monday.

Russia's demand was "a unilateral and clear breach of existing contracts," Habeck, who is also the German minister for economic affairs and climate action, said after a virtual meeting of the G7 energy ministers.

We will not be divided, and the response of the G7 countries is clear ... The contracts will be respected.

Contracts that had been concluded should continue to apply, said Habeck. "A payment in rubles is not acceptable," he added, urging companies involved not to follow Russia's demands.

"We will not be divided, and the response of the G7 countries is clear," said Habeck. "The contracts will be respected."
