Powerful Western countries aren’t done trying to squeeze Russian President Vladimir Putin as punishment for his invasion of Ukraine.

The Group of Seven countries announced new economic sanctions on Sunday, further limiting Moscow’s ability to export goods, kneecapping its propaganda services, and phasing in new limits on its oil and gas industry. President Joe Biden met with G-7 leaders via a video call from his home in Delaware on Sunday to discuss the new restrictions.

“Our unprecedented package of coordinated sanctions has already significantly hindered Russia’s war of aggression by limiting access to financial channels and ability to pursue their objectives,” the group said, according to remarks released by the White House. “We will continue to impose severe and immediate economic costs on President Putin’s regime for this unjustifiable war. We collectively commit to taking the following measures, consistent with our respective legal authorities and processes.”

The countries followed the European Union’s efforts to choke off Russia’s most important revenue stream by announcing plans to phase out or outright ban imports of Russian oil. Europe was slow to push for oil and gas restrictions early on because of its dependence on Russian energy. However, as the United States has stepped up promises to try and fill the gap the sanctions created, countries have been more willing to turn off Russia’s spigots.

Former State Department official Edward Fishman told Reuters the G-7 countries backing the EU embargo were important for its success.

"I think the next step is going to be the United States working with the EU and the rest of the G7 to globalize that campaign against Russia's oil sales," Fishman said.

The U.S. also levied sanctions on two Gazprombank officials, specifically — an effort, according to one Biden official who spoke with reporters, to “create a chilling effect.” Gazprombank is the third-largest bank in Russia.

“This is not a full block. We’re not freezing the assets of Gazprombank or prohibiting any transactions with Gazprombank,” the official said. “What we’re signaling is that Gazprombank is not a safe haven, and so we’re sanctioning some of their top business executives.”

Besides trying to stymie its economy, G-7 leaders also aimed to hinder Moscow’s media environment, sanctioning television stations that are directly or indirectly state-controlled, including Joint Stock Company Channel One Russia, Television Station Russia-1, and Joint Stock Company NTV Broadcasting company.
