Boris Johnson has asked other Western leaders to come together ahead of negotiations on Ukraine’s issue.
He said a “overwhelming display of Western unity” was essential ahead of his trip to Germany, where he will give a speech in Munich tomorrow.
The world’s leaders are gathering in the city for an annual security summit, but Russia is not among them this year.
With nearly 130,000 troops stationed along the Ukrainian border, Western allies have warned that Russia may invade the country at any time. Russia has rejected any intentions for an invasion, accusing the West of being “hysterical.”
Moscow stated that it was conducting military drills and that some troops had recently been returned to their regular locations.
Western nations, on the other hand, said they had observed no signs of Russian force departure, with US officials raising their assessment of Russian soldier numbers on Friday.On Saturday, Mr Johnson will fly to Munich, where he will address at the Munich Security Conference among other world leaders.
German Chancellor Olaf Scholz and US Vice-President Kamala Harris are among the Western officials attending the three-day gathering.
Mr Johnson would meet with a number of European partners to discuss the Western reaction, according to Downing Street.
However, due to escalating tensions along Ukraine’s borders, Russia will not be officially represented at the summit for the first time since 1999.
Mr Johnson stated ahead of his trip to Germany that “diplomacy can still prevail” in preventing conflict.
“There is still a possibility to avoid needless murder,” he concluded, “but it will take an outpouring of western unity unlike anything we’ve seen in recent history.”
Allies must speak to Russian President Vladimir Putin “with one voice” to emphasize “the enormous price he will pay for any further Russian invasion of Ukraine,” according to the PM.
Mr Johnson had previously stated that if Russia invaded Ukraine, Western countries would apply “extremely harsh” sanctions.
New legislation was also announced by the government, allowing the UK to expand its own sanctions against the country.
In addition, despite mounting pressure on ministers over the UK’s ties to Russia, the Home Office has withdrawn a visa scheme that offered wealthy foreign investors fast-track status.
Labour has requested that an ongoing examination of visas issued between 2008, when the system was first implemented, and 2015, when applicant checks were enhanced, be made public immediately.
The Liberal Democrats have also urged a “clear schedule” for cancelling visas for those Russians “identified as constituting a national security concern.”
