"I am deeply concerned by Russia's new law on 'undesirable' non-governmental organisations, which has just been signed into law by President Putin," said PACE President Anne Brasseur.
This law makes it easier for the government to shut down foreign and international NGOs, citing national security, and punish their workers with up to six years in prison.
"Following on from the already-worrying 'foreign agents' law, I fear these new powers will further restrict the work of civil society in Russia and stifle independent voices."
"The definition of 'undesirable' is not at all clear. I am appalled that - once again - Russians appear to be being deprived of rights, such as legal certainty and due process, that all Europeans are entitled to under the European Convention on Human Rights."
