French presidential envoy Jacques Audibert and his German counterpart Christoph Heusgen arrived in Kiev yesterday as part of a sudden upsurge in efforts to resolve one of Europe's deadliest crises since the 1990s Balkans wars.
US President Barack Obama and Russia's Vladimir Putin -- their relations nearing chills not witnessed since the end of the Cold War -- discussed the conflict during a rare but wide-ranging phone conversation on January 13.
Two different Ukrainian sources said Audibert and Heusgen met Poroshenko for the second time in two days on Tuesday after first flying to Moscow for a visit whose details have not been disclosed.
"Right now, all our partners are trying to understand how to end this stalemate because in reality, there has been no improvement," a high-ranking Ukrainian diplomat told AFP on condition of anonymity.
The Europeans separately met Ukrainian peace negotiators to gauge their commitment to an all-but-abandoned peace and political reconciliation agreement that Berlin and Paris helped Moscow and Kiev strike in February 2015.
The Ukrainian diplomat said the two envoys also visited "practically all" lawmakers to see whether they intended to pass a stalled Western-backed constitutional amendment granting special status to rebel-run parts of the eastern regions of Lugansk and Donetsk.
Kiev and the insurgents last week signed on to a new truce meant to quell violence that has claimed the lives of more than 9,000 people -- most of them civilians -- since April 2014.
But the Russian president admitted for the first time last month that there were "people (in Ukraine) who work on resolving various issues there, including in the military sphere.
