With Washington eyeing new sanctions against Russia, Moscow has been preparing to renew legislation intended to make life easier for Russian businesses keen to move their money home, Reuters said.

It would see businesses freed from a 13 percent profit tax on funds repatriated from abroad, among other penalties.

"On numerous occasions we have encountered attempts to freeze assets... in an unjustified and unlawful manner. This is achieved using direct sanctions," presidential press secretary Dmitry Peskov told reporters in a conference call on Tuesday.

"The president is backing an initiative which will create comfortable conditions for businesses interested in seizing the opportunity to return funds to Russia," he said.

The original amnesty was introduced in 2015 amid huge capital outflows during a climate of deteriorating relations with the West over the conflict in Ukraine and worsening economic conditions following falls in the oil price.

Among other tools to encourage the return of money will be a sovereign eurobond issue next year, aimed in part at providing a way for businesses to repatriate funds.
