The Biden administration announced Friday that it will move to freeze the assets of President Vladimir Putin and Foreign Minister Sergey Lavrov, following the European Union and Britain in directly sanctioning top Russian leadership.

The Treasury Department announced the sanctions shortly after the EU said it had also approved an asset freeze against Putin and Lavrov as part of a broader package of sanctions against Russia for the invasion of Ukraine. British Prime Minister Boris Johnson also told NATO leaders during a call Friday that Britain would move to impose sanctions against Putin and Lavrov.

It wasn’t immediately clear how impactful an asset freeze would be on Putin or Lavrov, but the direct action targeting the Russian president was meant to be seen as a warning to Putin that he could emerge as an international pariah if he doesn’t end the invasion of Ukraine.
