The United States and European Union plan to impose new sanctions against Russia this week, including penalties targeting key sectors of the Russian economy, the White House said Monday.
The show of Western solidarity comes as the US accuses Russia of ramping up its troop presence on its border with Ukraine and shipping more heavy weaponry to pro-Moscow separatists in eastern Ukrainian cities.
US President Barack Obama and the leaders of Britain, Germany, France and Italy discussed the crisis during a rare joint video teleconference on Monday. The discussion follows days of bilateral talks on how to implement tougher sanctions after the downing of a passenger jet in eastern Ukraine, an attack the US says was carried out by the separatists.
The US and European sanctions are likely to target Russia's energy, arms and financial sectors. The EU is also weighing the prospect of levying penalties on individuals close to Russian President Vladimir Putin, who appears to only be deepening Russia's role in destabilizing Ukraine.
"It's precisely because we've not yet seen a strategic turn from Putin that we believe it's absolutely essential to take additional measures, and that's what the Europeans and the United States intend to do this week," said Tony Blinken, Obama's deputy national security adviser.
Europe, which has a stronger trade relationship with Russia than the US, has lagged behind Washington with its earlier sanctions package, in part out of concern from leaders that the penalties could have a negative impact on their own economies. But a spokesman for British Prime Minister David Cameron said following Monday's call that the West agreed that the EU should move a "strong package of sectoral sanctions as swiftly as possible."
French President Francois Hollande said in a statement that the Western leaders "regretted Russia has not effectively pressured separatists to bring them to negotiate nor taken expected concrete measures to assure control of the Russian-Ukrainian border."
The US penalties are expected to be imposed after Europe finalizes its next moves. Neither set of penalties is expected to fully cut off Russian economic sectors from the West, an options US officials have said they're holding in reserve in case Russia launches a full-on military incursion in Ukraine or takes a similarly provocative step.
As the West presses ahead with new sanctions, US officials say Russia is getting more directly involved in the clash between separatists and the Ukrainian government. Blinken said Russia appeared to be using the international attention focused on the downed Malaysia Airlines plane as "cover and distraction" while it moves more heavy weaponry over its border and into Ukraine.
"We've seen a significant re-buildup of Russian forces along the border, potentially positioning Russia for a so-called humanitarian or peace-keeping intervention in Ukraine," Blinken said. "So there's urgency to arresting this."
Nearly 300 people were killed when the Malaysian plane was shot down by a missile on July 17. The West blames the separatists for the missile attack and Russia for supplying the rebels with equipment that can take down a plane.
Other leaders participating in Monday's call were German Chancellor Angela Merkel and Italian Prime Minister Matteo Renzi. The White House said the leaders also discussed the stalled efforts to achieve a cease-fire between Israel and Hamas, the need for Iraq to form a more inclusive government and the uptick in security threats in Libya.
