Germany is asking Ukraine to propose a new offer to resolve a dispute with Russia over a $3 billion bond default after President Vladimir Putin’s government rejected a proposal put forward last month.


The Finance Ministry in Berlin, which is mediating talks between the two former-Soviet neighbors over the debt, is urging Ukraine to compromise, according a person with knowledge of the negotiations, who asked not to be identified because the details are private. The latest offer to resolve the dispute was “unacceptable” because it contained terms that were worse than those given to private creditors in a $15 billion restructuring last year, Russia’s Finance Ministry said in an e-mailed response to questions Tuesday.


The mediation effort is a sign that Ukraine is trying to reach an out-of-court compromise to a dispute that’s deepened the rift between the neighbors that began in 2014 when Russia annexed Crimea. The government in Moscow refused to take part in Ukraine’s debt overhaul last year because it wanted to be treated more favorably than private investors. Bondholders accepted a 20 percent principal writedown as part of that agreement.


A spokeswoman for Ukraine’s Finance Ministry couldn’t immediately be reached by phone to comment on the status of mediation efforts.


Lawsuit Threat


Since Ukraine failed to redeem the bond on Dec. 20, Russia has threatened to initiate legal proceedings in the U.K. The filing of the lawsuit has been delayed, Russian Finance Minister Anton Siluanov told reporters in Moscow on Feb. 5. Both sides said last month that they are open to out-of-court discussions.


Ukraine is barred from paying Russia back in full under the terms of its restructuring agreement, which was reached to enable the country to qualify for a $17.5 billion International Monetary Fund rescue package to help it avert bankruptcy as separatist unrest hobbled its economy. The terms of that funding also require Ukraine to negotiate in “good faith” with Russia over the defaulted bond.


In comments on Tuesday, Svetlana Nikitina, an aide to Siluanov, said Russia received a letter from Germany’s Finance Ministry with a solution to resolve the debt dispute.


Since there’s been no offer directly from Ukraine, it “could in no way be regarded as an attempt to begin good-faith negotiations,” she said. “The conditions of the offer were such that they could not be considered seriously, since they are worse that those offered to commercial creditors.”


Bond Slump


Putin proposed in November to allow Ukraine to settle the debt in three $1 billion installments from 2016 to 2018, but the plan fell through after the U.S. refused to offer the financial guarantees that Russia requested. Ukrainian Finance Minister Natalie Jaresko made the country’s latest offer at the World Economic Forum in Davos last month, according to the person familiar with the negotiations.


The country’s restructured Eurobonds have slumped this month amid a government shakeup that began when a reform-minded economy minister resigned on Feb. 3 after accusing presidential party members of corruption. The yield on bonds maturing in September 2019 jumped above 12 percent on Tuesday for the first time since they were issued in November.


“At the moment, with concerns over domestic political stability in Ukraine, the country does not need further uncertainty” around the bond dispute with Russia, Timothy Ash, head of Europe, Middle East and Africa credit strategy at Nomura International Plc in London, said in an e-mailed note.
