The West should consider measures to stop Russia using its gold reserves, the prime minister has said.
Boris Johnson’s comments came as the UK announced sanctions on 65 more groups and individuals, including a private military firm and a major Russian bank.
Speaking ahead of a Nato summit, the PM said the UK and the West must “tighten the economic vice” on Vladimir Putin.
He said Russia crossed “red lines” by targeting Ukrainian civilians and tough steps now could help shorten the war.
In addition to the new raft of financial sanctions, the UK government has announced plans to send 6,000 more missiles to Ukraine.
Leaders from Nato, the EU, and the G7 are holding emergency meetings in Brussels to discuss the ongoing situation in Ukraine.
The Nato summit is expected to approve the formation of four new battlegroups in eastern Europe, while Ukrainian President Volodymyr Zelensky used a virtual address on Thursday morning to urge the bloc to increase its supply of military equipment.
Ahead of the talks, Mr Johnson said that, by deliberately bombing civilian centres, Putin had “already crossed the red line into barbarism”.
“We’ve got to step up. We’ve got to increase our support,” he said.
“We’ve got to tighten the economic vice around Putin, sanctioning more people today, as we are, sanctioning the Wagner Group, looking at what we can do to stop Putin using his gold reserves.”
The Wagner Group, a private military firm thought to function as an arms-length unit of the Russian military, was among the 65 entities hit by new sanctions announced by the UK government on Thursday.
Also targeted were Gazprombank, the country’s third-largest bank and one of the main channels for payments for Russian oil and gas, and the state-run shipping firm Sovcomflot.
The reported step-daughter of Russian foreign minister Sergei Lavrov, Polina Kovaleva, who is thought to own a London property worth an estimated £4million, was also targeted by the measures.
In his speech to Nato leaders, Mr Zelensky called on them to give or sell Ukraine more tanks and anti-aircraft defence systems.
“I don’t want to blame Nato. I understand, this is not you,” he said. “These are not your missiles or bombs which are destroying our cities.
“I simply want you to know the alliance still can prevent Ukrainian deaths… by providing us all the munitions we are asking for.”
The summit follows an announcement by the UK government that it would be providing Ukraine with an additional 6,000 anti-tank and other missiles.
The UK has already sent 4,000 anti-tank weapons, but will now send another 3,000, plus a similar number of what Downing Street described as “high explosive missiles”.
The prime minister is also expected to set out plans to offer more help to Ukraine with intelligence and longer-range combat.
Ukrainian officials indicated this week the country’s armed forces currently have the equipment they needed to stop tanks at short range, but needed more to help to do the same over longer distances.
The UK will also send an additional £25m in aid to help Ukraine pay the salaries of its armed forces.
