UK pushes against Russia in northern European summit

British Prime Minister Boris Johnson will next week host a summit with leaders from Nordic countries and Russia's Baltic neighbours, as Norway hosts one of NATO's biggest military exercises since the Cold War.

"Exercise Cold Response" will see more than 30,000 troops from 27 nations training in sub-zero temperatures from Monday. 

In a statement Saturday, Downing Street said in parallel to the drills, Johnson would convene leaders from the Joint Expeditionary Force, a coalition of 10 states focused on security in northern Europe.

After dinner on Monday at his country retreat of Chequers, the prime minister will convene a summit in London of the JEF countries on Tuesday, it said.

"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.

"Ensuring we are resilient to (Vladimir) Putin's threats needs to go beyond our military footing -- together alongside our North and Baltic Sea partners we must ensure we are insulated from Russia's interference and impact on our energy supplies, economy and values."

The JEF, set up in 2012, is made up of NATO members Britain, Denmark, Estonia, Iceland, Latvia, Lithuania, the Netherlands and Norway, plus non-members Finland and Sweden.

The group has been staging its own UK-led military exercise in the Baltic Sea, to demonstrate JEF nations' "freedom of movement" in the strategic zone adjacent to Russia. 

At this week's summit, the JEF leaders are expected to agree to an "enhanced programme" of exercises in the Arctic, North Atlantic and Baltic Sea, the Downing Street statement said.
