Kiev:
Ukraine President Petro Poroshenko appealed to Russia's Vladimir Putin on Wednesday while Washington threatened tougher measures should Moscow fail to rein in separatists mounting a new offensive in the east of the ex-Soviet republic.
Poroshenko's personal letter and US Treasury Secretary Jack Lew's warning came one day after European Union leaders unanimously backed pursuing more economic restrictions against Russia for its alleged meddling in Ukraine.
Greece and Cyprus later distanced themselves from the statement but are not expected to fight new penalties the bloc's 28 foreign ministers will draft in Brussels on Thursday.
Western sanctions and a coinciding slide in oil prices have plunged Russia into recession and seen Standard and Poor's slap a junk rating on Moscow's foreign currency debt.
The downgrade threatens to further alienate Western investors as the grade is Russia's worst since the start of Putin's 15 year rule.
Yet the pain appears to have done little to alter Putin's tough approach to his western neighbour or to dent Russians' monumental trust in the Kremlin chief.
Pro-Moscow rebels in Ukraine last week defiantly pulled out of peace talks and vowed an offensive on a strategic government held port city that provides a direct land bridge to Ukraine's Russian occupied Crimea peninsula.
A rocket assault on the port of Mariupol left 31 civilians dead at the weekend, in a major escalation of the conflict. The separatist fighters have denied being responsible for the deaths but international monitors have said the rocket fire came from rebel-held territory.
The new eastern offensive has also seen separatists in the Lugansk and Donetsk regions try to link up their armies by taking over isolated pockets of land still controlled by government troops.
The Kiev military and local pro-government officials said five soldiers and at least three civilians had died in clashes over the past 24 hours. The United Nations believes the latest spiral of violence has pushed the war's death toll above 5,100.
Poroshenko's office said his letter to Putin demanded that Moscow immediately rein in the offensive and fulfil the terms of a long-ignored peace plan it signed with Kiev and two top separatist leaders in Belarus in September.
"On Monday, I sent a letter to President Putin whose main elements included not only the demand to cease fire and implement the Minsk Agreements but also to release Nadezhda (Nadia) Savchenko and all the hostages," the presidency quoted Poroshenko as saying.
The female Ukrainian pilot is alleged to have been abducted by the rebels and smuggled to Moscow where she is now being detained.
She is charged with involvement in an attack that killed two Russian reporters in June. Savchenko's lawyers said she went on a hunger strike in protest at her detention on December 13.

There was no immediate reply to Poroshenko's letter from the Kremlin.
But Putin this week accused NATO of launching a proxy war in eastern Ukraine designed to weaken Russia and sever the two country's ancient relations.
US finance chief Lew said during a visit to Kiev that Washington would prefer to ease its worst crisis with Moscow since the Cold War.
"Our first choice is a diplomatic resolution that allows us to lessen sanctions," Lew told reporters after meeting his Ukrainian counterpart Natalie Jaresko.
"But we are prepared to do more if necessary. To that end, we'll continue to work with our allies to increase the pressure on Russia."
Moscow flatly denies backing the insurgents and claims the sanctions are an attempt to punish Russia for going against US policies.
