After more than seven hours of negotiations, the leaders of Ukraine and Russia agreed to exchange all prisoners before Dec. 31, disengage weapons in three locations on the front line and to implement the so-called Steinmeier Formula into Ukrainian legislation.

Such was the outcome of the Normandy Four meeting in Paris on Dec. 9, the first such meeting since October 2016. It was also the first meeting of Ukraine’s President Volodymyr Zelensky with his Russian counterpart Vladimir Putin, with leaders of France and Germany joining them.
