British Prime Minister Rishi Sunak condemned Russia's "barbaric war" against Ukraine during the G20 summit, Sky News writes.

 The British prime minister made the comments at the first meeting of the G20 on Tuesday, criticizing the absence of the Russian president from the talks on the Indonesian island of Bali.

 "It's remarkable that Putin didn't think it was possible to join us here," he said. "Maybe if he did, we could start figuring things out."

 Sunak said that Russia should "leave Ukraine and put an end to this barbaric war."

 "Great Britain rejects this aggression. We will support Ukraine as long as necessary," he said.

 Sunak also reprimanded Russia, saying that "countries should not invade their neighbors."

 "It's very simple - countries should not invade neighboring countries, they should not attack civilian infrastructure and civilians, and they should not threaten nuclear escalation," he said.

 According to the British government, Sunak agreed during the G20 summit to strengthen global food and energy security by: reducing Russia's ability to use energy as a weapon, accelerating the global transition to clean energy, and investing in sustainable food.

 As reported, during the summit, Sunak will confirm the financial support of Ukraine from Great Britain.

 Putin sent the Minister of Foreign Affairs of the Russian Federation Sergey Lavrov to the negotiations instead of him.
