Russia on Monday said domestic exporting companies would have to sell 50 percent of their income in foreign currency, a reduction from 80 percent, after Moscow said the ruble had stabilized. 

After the West slapped sanctions on Russia over the start of Moscow's military offensive in Ukraine in February, financial authorities introduced harsh capital controls. They ordered exporting companies to sell 80 percent of their export earnings to buy rubles, among other measures.

Since then, the ruble has staged a spectacular rebound and strengthened around 30 percent against the dollar.

On Monday, the finance ministry, citing a government commission, said exporting companies would now be required to sell 50 percent of their income in foreign currency.

"This is due to the stabilization of the ruble exchange rate and the achievement of a sufficient level of foreign currency liquidity in the domestic foreign exchange market," the finance ministry said.

President Vladimir Putin has repeatedly claimed that Russia's economy has managed to weather the barrage of unprecedented Western sanctions.
