Switzerland has announced that it will relinquish its commitment to “Swiss neutrality” in favor of adopting sanctions against Russia, Swiss Federal President Ignazio Cassis said Monday, adding that Swiss sanctions would be in line with those adopted by the European Union.

“The Russian attack is an attack on freedom, an attack on democracy, an attack on the civilian population and an attack on the institutions of the free state. This is unacceptable under international law, this is not politically acceptable, and this is morally unacceptable,” Cassis added.

Speaking after an extraordinary meeting of the Swiss Federal Council, Cassis stressed that “in these dark days,” Switzerland stands in solidarity with the Ukrainian people and hopes the sanctions will encourage the Kremlin to “change its mind.”

“Playing in the hands of an aggressor is not neutral. Having signed the Geneva convention on human rights, we are bound to the humanitarian order,” Cassis said. “Other democracies will be able to rely on Switzerland; those who stand for international law will be able to rely on Switzerland; a country that upholds human rights will be able to rely on Switzerland.”

Switzerland will freeze the assets of “registered persons” and will also impose entry bans on those highlighted by the European Union’s sanctions package, according to the Swiss Federal President.

Cassis said Switzerland closed its airspace to all flights from Russia, including private jets, with the exception of humanitarian flights, search flights and emergency situations.

Swiss Justice Minister Karin Keller-Sutter said the entry ban would have an impact on “Russian or Ukrainian oligarchs who are very close to Russian President Vladimir Putin.”

“These are five people with strong economic connections to Switzerland,” Keller-Sutter highlighted, but said for privacy reasons he did not name the oligarchs.
