The letter, sent to the European Union’s High Representative for Foreign Affairs, Josep Borrell, was signed by the foreign ministers of the Czech Republic, Estonia, Finland, Lithuania, Latvia, Poland, Sweden, and Romania.

Officials said it was also supported by the Netherlands, France, Ireland, and Denmark, bringing total support to 12 countries.

“Mr. Navalny’s death is yet another sign of the accelerating and systematic repression in Russia. This calls for collective action,” the foreign ministers’ letter said.

“We believe there is a strong case for a separate Russia-specific sanctions regime designed to address the situation in the country,” the letter said.

“The new regime would provide a solid legal basis to list individuals from Russia’s repressive state apparatus, including those involved in politically motivated rulings against members of civil society and the democratic opposition and their subsequent detention, such as those responsible within the judicial chain [prosecutors, courts, penitentiary],” it said.

Navalny paid the ultimate price for advocating everything the EU represents. Yet, 12 days after his murder, we have not taken countermeasures. We need his courage. We must rebuild Ukraine using Russia's frozen assets & support @EU2024BE with new sanctions. pic.twitter.com/xqd3aiOlmu

Navalny, 47, died on February 16 in an Arctic penal colony where he was serving a lengthy jail sentence. His wife and supporters have accused Russian despot Vladimir Putin of causing his death, an accusation the Kremlin denies. His death certificate says he died of natural causes, according to his supporters.
