Russia plans to significantly tighten the rules governing the income received by those deemed “foreign agents” and of those who speak negatively about Russia after leaving the country, the speaker of the Russian parliament said on Thursday.

Axar.az reports that , citing Reuters,Vyacheslav Volodin, the speaker of the lower house of the Russian parliament, said that the Duma was working on tightening the rules over copyright and intellectual rights payments to foreign agents by forcing them to use special ruble accounts for such payments.

“Those who destroy Russia by insulting its citizens, the participants of the special military operation, should not enrich themselves at the expense of our country,” Volodin said.

It should be noted that a total of 881 people and organizations are listed as foreign agents by the Russian justice ministry, including former billionaire Mikhail Khodorkovsky, Nobel prize winner Dmitry Muratov and prominent YouTube blogger Yuri Dud.
