British Prime Minister Boris Johnson will host leaders from countries along Russias northwestern flank next week to discuss ways they can respond to President Vladimir Putins invasion of Ukraine, including finding new ways to isolate Russias economy. The leaders from countries in the Joint Expeditionary Force, a British-led grouping made up of Denmark, Estonia, Finland and Iceland, Latvia, Lithuania, the Netherlands, Norway, and Sweden will meet for talks in London on Tuesday. The leaders are expected to agree to more military exercises in the North Atlantic and Baltic Sea and will discuss the war in Ukraine and energy security, Johnsons office said, Reuters reported. "European security has been shaken by the attack of Russia on Ukraine, and alongside our partners, we will take action to ensure we emerge stronger and more united than before," Johnson said in a statement. "Ensuring we are resilient to Putins threats needs to go beyond our military footing - together alongside our North and Baltic Sea partners we must ensure we are insulated from Russias interference and impact on our energy supplies, economy and values." Britain has imposed sanctions on hundreds of Russian individuals and entities, promised to phase out Russian oil imports and banned Russian companies from raising debt and equity in its financial center.
