The leaders of Ukraine, Russia, France and Germany have agreed to send OSCE observers to areas of Ukraine where violations of a truce have been reported, Kiev says.
In a statement, Ukrainian President Petro Poroshenko says the leaders – who spoke by phone – backed Kiev’s proposal to begin with 10 locations in the east.
A statement on the Russian presidential website did not mention the proposal.
Separately, the EU brokered a deal which secures Russian gas for Ukraine.
Russia had threatened to cut off gas supplies unless it received outstanding pre-payments from Ukraine.
Now Ukraine’s gas company Naftogaz has agreed to pre-pay for gas to cover Ukrainian needs until the end of March. Russia’s Gazprom plans to deliver up to 114m cubic metres (4,026m cu ft) daily.
However, there was no agreement on gas deliveries to rebel-held areas in eastern Ukraine. Ukraine has protested over direct Russian gas deliveries to the pro-Russian separatists controlling the Donetsk and Luhansk regions.
Ukraine is a vital transit country for Russian gas exports to the EU. About 40% of EU gas imports come from Russia.
EU Commission Vice-President Maros Sefcovic said Monday night’s agreement meant “the supply of gas to the EU markets remains secure”.
