Steps toward a détente in the Donbas were agreed in Paris Monday night by Presidents Putin and Zelenskiy. Within one month, a ceasefire is to be imposed, new civilian crossing points are to be opened, an ‘all for all’ prisoner swap is to talk place, and soldiers are to pull back at three sections on the 500 km line of control. If the killing stops, it is conceivable that the presidents could announce at their next meeting, in April, a resumption in Donbas trade. This would help Mariupol, the only port for Donetsk region, and DTEK, which is cut off from several of its coal mines.
