The talks are taking place in the so-called “Normandy Format,” with French President Emmanuel Macron and German Chancellor Angela Merkel mediating the negotiations. Russian President Vladimir Putin and Ukrainian President Volodymyr Zelenskiy will meet for the first time at the summit.
The Normandy group has not been held since October 2016, a reflection of how efforts to end the war have stalled, with the conflict essentially unchanged for years as soldiers and civilians continue to be killed.
The war began after Russian annexed Crimea in 2014 and then seized control of two large eastern regions of Ukraine using pro-Russian separatists as proxies. Since then, 13,000 people — about a quarter of them civilians — have been killed more than 2 million displaced, according to the U.N.
