The Russian Prosecutor General’s Office has recognized George Soros’s Open Society Institute and another affiliated organization as undesirable groups, banning Russian citizens and organizations from participation in any of their projects.

In a statement released on Monday, prosecutors said the activities of the Open Society Institute and the Open Society Institute Assistance Foundation were a threat to the foundations of Russia’s Constitutional order and national security. They added that the Justice Ministry would be duly informed about these conclusions and would add the two groups to Russia’s list of undesirable foreign organizations.

Prosecutors launched a probe into the activities of the two organizations - both sponsored by the well-known US financier George Soros - in July this year, after Russian senators approved the so-called “patriotic stop-list” of 12 groups that required immediate attention over their supposed anti-Russian activities. Other groups on the list included the National Endowment for Democracy; the International Republican Institute; the National Democratic Institute; the MacArthur Foundation and Freedom House.

In late July, the Russian Justice Ministry recognized the US National Endowment for Democracy as an undesirable group after prosecutors discovered the US NGO had spent millions on attempts to question the legitimacy of Russian elections and tarnish the prestige of national military service.

The Law on Undesirable Foreign Organizations came into force in early June this year. It requires the Prosecutor General’s Office and the Foreign Ministry to draw up an official list of undesirable foreign organizations and outlaw their activities. Once a group is recognized as undesirable, its assets in Russia must be frozen, its offices closed and the distribution of any of its materials must be banned.

If the ban is violated, the personnel of the outlawed group and any Russian citizens who cooperate with them could face heavy fines, or even prison terms in the case of repeated or aggravated offences.
