European Commission President Ursula von der Leyen announced on Sunday that the European Union’s 19th package of sanctions against Russia is set to be unveiled in early September.

“As long as the bloodshed in Ukraine continues, Europe will maintain diplomatic and, in particular, economic pressure on Russia,” von der Leyen said during a joint press briefing with Ukrainian President Volodymyr Zelenskyy at the Berlaymont building in Brussels.

“We have adopted 18 packages so far, and we are advancing preparation for the 19th. This package will be forthcoming in early September,” she said.

Von der Leyen stressed that existing measures have proven effective against Russian President Vladimir Putin’s war effort, highlighting that frozen Russian assets have already been redirected to support Ukraine.

“We need to prepare the 19th package so that Russia sees that we are serious,” she said. “We must continue to limit Russia’s potential.”

She added that the EU would keep targeting Russia’s war economy “to bring President Putin to the negotiation table.”

Von der Leyen is set to be among the European leaders who will accompany Zelensky when he meets with U.S. President Donald Trump at the White House on Monday.

“These are challenging times,” von der Leyen said. “Only Ukraine can choose its own destiny, but Ukraine can always count on Europe,” she said.
