The country is still on the verge of further violence. While Russia's President Vladimir Putin appears to have backed down from military action on the Ukrainian borders, there is still unrest in plenty of Ukraine outside the Crimea, and potential for this to spread.

Bringing forward Crimea's referendum on whether to join Russia from March 30th to 16th, after the region's parliament voted to join Russia, may raise the stakes again.

"If you look at the strategies for most big multinationals, Russia is the key to the Central and Eastern Europe market. If Russia goes wrong here, it will have a global effect," Richard Martin, managing director, IMA Asia, told CNBC.
"You've also got a second big country in the region, Turkey, where things are going wrong politically. Russia is a big part of sales and it will have a negative impact if it goes wrong."
