(Bloomberg) -- Ukraine’s foreign minister called on allied nations to provide a “deterrence package” that would make President Vladimir Putin reconsider an invasion of his country, as Russia accused Kyiv of nurturing plans to attack Moscow-backed separatists in the east of the country.

Meeting Secretary of State Antony Blinken in Stockholm, Dmytro Kuleba said partners should provide support “that will make President Putin think twice before resorting to military force.” But he also pledged restraint, saying Ukraine has “no intentions to provoke them or to hold any military operations in Donbas.”

The Kremlin, however, stepped up its rhetoric accusing Kyiv of planning to use force against the Russian-backed separatists in Donbas. “The risk of military action in Ukraine is still high,” spokesman Dmitry Peskov told reporters Thursday. “We see an increasing intensity of provocative actions on the line of contact” between Ukrainian forces and the separatists, he said.

The U.S. and its allies accuse Russia of massing tens of thousands of troops for a possible invasion of Ukraine, an intention the Kremlin denies. So far, Putin has shown little sign that he’s deterred by weeks of warnings from the U.S. and its allies of potentially painful consequences for such a move. Instead, the Kremlin has accused North Atlantic Treaty Organization of threatening its security and Ukraine of nurturing plans to move on the separatists, which Kyiv dismisses. 

Lavrov Meeting

Blinken is set to meet Russian Foreign Minister Sergei Lavrov later Thursday to warn against any further aggression and gauge the country’s intentions.

Blinken said Wednesday at a NATO conference in Latvia that the U.S. would impose “high-impact economic measures that we’ve refrained from using in the past” if Russia invaded its neighbor. At the same time, he sought to offer Russia a diplomatic off-ramp, saying the sides should recommit to the 2015 Minsk truce accords that offered a framework for resolving the conflict. Moscow has accused Kyiv of seeking to sabotage those, a charge Ukraine rejects. 

Meeting Kuleba on Thursday, Blinken said the U.S. has “deep concerns about the aggressive posture that Russia has taken once again toward Ukraine.”

Officials haven’t detailed what such a deterrence package might look like, though the U.S. provides tens of millions of dollars in security assistance to Ukraine every year. In March, the U.S. announced a $125 million defense package for Ukraine, and in Washington last month, Kuleba said Ukraine is looking for help bolstering defense, “be it intelligence sharing or air defense systems or anything else.”

Separately, Ukraine said Wednesday it’s seeking long-term financial aid from the European Union.
