KYIV, Dec 12 - The Group of Seven economic powers told Russia on Sunday to “de-escalate” its military buildup near the Ukrainian border, warning that an invasion would have “massive consequences” and inflict severe economic pain on Moscow, The Associated Press reported.

G-7 foreign ministers, joined by the European Union’s foreign affairs chief, issued a joint statement declaring themselves “united in our condemnation of Russia’s military buildup and aggressive rhetoric towards Ukraine.”

The G-7 called on Russia to “de-escalate, pursue diplomatic channels, and abide by its international commitments on transparency of military activities,” and praised Ukraine’s “restraint.”

“Any use of force to change borders is strictly prohibited under international law. Russia should be in no doubt that further military aggression against Ukraine would have massive consequences and severe cost in response,” the statement said.

Russia’s movement of weapons and troops to the border region dominated weekend talks among foreign ministers from the G-7 wealthy democracies in the English city of Liverpool.

The U.S. and its allies worry that the buildup could be precursor to an invasion and have vowed to inflict heavy sanctions on Russia’s economy if that happens.

Moscow denies having any plans to attack Ukraine and accuses Kyiv of its own allegedly aggressive designs.

British Foreign Secretary Liz Truss, the conference host, said the G-7 was sending a “powerful signal to our adversaries and our allies.”

The statement promised a “common and comprehensive response” but contained no details. Truss said the G-7 was “considering all options” when it came to economic sanctions.

The U.S. and its allies have played down talk of a military response to defend Ukraine, with efforts focusing on tough sanctions that would hit the Russian economy, rather than just individuals.

In the U.S., reporters asked President Joe Biden on Saturday about the possibility of sending combat troops to Ukraine, and he said that idea was never considered. “Are you ready to send American troops into war and go into Ukraine to fight Russians on the battlefield?” he said.

Biden, who spoke to Russian President Vladimir Putin last week, said he had made clear that in the event of an invasion, “the economic consequences for his economy are going to be devastating. Devastating.”

Truss said Biden had made clear to Putin that the U.S. stance “carries the support of the G-7 countries as a whole. And that should be very concerning for Vladimir Putin.” (ap/ez)
