Cyprus is hoping for a EUR 5 billion bailout package from Russia. Unable to raise debt on international capital markets and heavily exposed to the financial woes of Greece, which is at the heart of the euro zone's debt crisis, Cyprus also sees enormous volumes of transit money channelled through offshore companies set up for Russian businesses.

Cyprus received 2.5 billion euros of credit from Russia last year.

The troubled Mediterranean island has also requested assistance from the euro-zone financial decision-making "troika" of the International Monetary Fund, the European Central Bank and the European Commission.

Russia's motives in extending such a huge credit line to Cyprus were dubious, said Anna Bodrova, an analyst at InvestCafe. They could include a desire to be involved in gas exploration projects or preserve the stability of a country that sees big money flows from large Russian companies, she added.

Cyprus is one of the biggest foreign investors in Russia because of the cash that is temporarily relocated to the island by Russian firms before being repatriated. There is a direct relationship between the oil price and the value of non-resident deposits in Cyprus.

"Russia has an interest in Cyprus being stable," said Alexander Osin, chief economist at Finam. "Whether the [transit money] is good or bad will be decided later."

The financial gap facing the government in Nicosia in the last six months of 2012 is likely to reach 15 billion euros, or 80 percent of gross domestic product, analysts at VTB Capital said in a report published Wednesday. The economy is forecast to contract by 1.5 percent this year.

Cyprus's economic and financial woes are already having an impacting on how some Russian companies perceive it as an offshore destination, a lawyer with a Western law firm in Moscow said.

The island has become less "user friendly" and there is concern about the possibility of currency controls being imposed, he added.

But others said that the fiscal woes have not yet materially affected the demand for offshore companies. The first six months of 2012 saw 9,445 new companies registered in Cyprus, compared to 9,999 in the same period in 2011, said Yekaterina Manskaya, a lawyer at Cliff Legal Services.

The island's financial crisis was not a significant factor in the slight decrease, she added.
