BBC: Russia, already teetering on the edge of recession, has a lot to lose from any economic sanctions imposed by Europe and the US - as does Europe, experts say.
The tense stand-off between Russia and the West over Crimea and Ukraine has led to sanctions being imposed on members of the Russian elite by the EU and the US.
US president Barack Obama has signed an order enabling economic sanctions against sectors of the Russian economy, and EU leaders are meeting in Brussels to consider their options.
"Russia can lose immensely out of this," says Paul Ivan, an analyst at Brussels-based think tank the European Policy Centre. "They are much more dependent on the European economy than we are on them."
Over half of Russia's budget comes from gas and oil it sends to the EU, making it vulnerable to any economic sanctions involving fossil fuel exports, Mr Ivan says.
By contrast, around 25% of European Union gas comes from Russia.
EU member states are linked to gas supplies flowing from countries such as Norway, making them less vulnerable to fluctuations in supply from Russia. » | Friday, March 21, 2014
