MOSCOW -- On Russian President Vladimir Putin's demand, the upper house of the Russian parliament on Wednesday canceled a resolution allowing the use of military in Ukraine, a move intended to show Moscow's eagerness to de-escalate tensions and avoid a new round of Western sanctions.
Putin had said his request, made a day earlier, was intended to help support the peace process in Ukraine, which began Friday with a weeklong cease-fire.
Putin needs to show his support for Ukrainian President Petro Poroshenko's peace plan ahead of Friday's European Union summit to avoid further Western sanctions. The EU has warned it could introduce new sanctions that would target entire sectors of the Russian economy if Moscow fails to help de-escalate the crisis.
The vote came as NATO foreign ministers gathered in Brussels, warning that more sanctions were possible and considering ways to bolster Ukraine's military.
German Chancellor Angela Merkel told lawmakers Wednesday that Putin's move to rescind the permission for using military force in Ukraine was an "important psychological point," but that progress toward a solution remains slow and EU is still prepared to increase sanctions.
Merkel, who was set to have a phone call with Putin, French President Francois Hollande and Poroshenko later in the day, said the EU will do everything possible to help find a diplomatic resolution, but added that "if nothing else helps, sanctions could return to the daily agenda, and this time at the third level."
Two previous rounds of U.S. and EU sanctions imposed asset freezes and travel bans on members of Putin's inner circle over Russia's annexation of Crimea. The next round, which would impose penalties for entire sectors of the Russian economy, could be far more crippling.
Maintaining pressure on the Kremlin, NATO's secretary general said Wednesday there are "no signs" Russia is respecting its commitments over Ukraine.
Speaking after the NATO foreign ministers meeting, Anders Fogh Rasmussen urged Russia to "take genuine and effective measures to stop destabilizing Ukraine ... create conditions for the peace plan to be implemented ... end its support for armed separatist groups, and ... stop the flow of weapons and fighters across its borders."
"This is a real opportunity to de-escalate the crisis caused by Russia's aggression, and Russia must step back in line with its international obligations," Rasmussen said.
He added that the meeting approved moves to help build Ukraine's military capacities, including by creating trust funds.
"We endorsed a package of additional measures to strengthen Ukraine's ability to defend itself," he said. "This includes the establishment of new trust funds to support defense capacity building in critical areas such as logistics, command and control, and cyber defense and to help retired military personnel to adapt to civilian life."
On Tuesday, Putin urged Ukraine to extend the truce and sit down for talks with the rebels. He argued that the Ukrainian demand that the insurgents lay down their weapons within a week was unrealistic, explaining that they would be reluctant to disarm for fear of government reprisals.
The Russian leader also called on Ukraine to adopt constitutional amendments and other legal changes that would protect the rights of Russian-speakers in the east.
Poroshenko promised Wednesday that he would submit draft constitutional amendments offering broader powers to the regions and voiced hope for quick approval by parliament. He said that the Russian parliament's move to rescind the sanction for the use of force was the result of his peace plan.
Speaking after a meeting of the NATO-Ukraine Council in Brussels, Ukrainian Foreign Minister Pavlo Klimkin hailed the Russian parliament's vote as a "positive step," but urged Moscow to also stem the flow of militants and weapons across the border. "It has to be stopped in order to enable further effective de-escalation of the situation," he said.
Ukraine and the West have accused Russia of supporting the rebellion with troops and weapons, but Moscow has denied that.
The cease-fire has been repeatedly broken by sporadic clashes, and it was violated again Tuesday when rebels used a shoulder-fired missile to down a Ukrainian military helicopter, killing nine servicemen. The attack, which came a day after the rebels pledged to respect the cease-fire, prompted Poroshenko to warn that he may end the truce ahead of time.
Putin's March 1 request to parliament for authority to use the military in Ukraine came days after Ukraine's pro-Russian president was chased from power following months of street protests. Russia sent troops that quickly overran Ukraine's Black Sea peninsula of Crimea, setting the stage for Russia to annex it after a hastily called referendum. In April, a mutiny erupted in eastern Ukraine, where pro-Russian insurgents seized official buildings, declared their regions independent and fought government troops.
