France, Germany and Poland "fell victim to the same destabilization strategy," the head of French diplomacy said in an interview on Saturday.
"On Monday, we will announce new cooperation against disinformation and Russian information attacks," the politician added.
The French Foreign Ministry summoned Russian Ambassador to Paris Alexei Meshkov last week, due to increasing Russian disinformation against France.
"We will transparently reveal to the public the tools of this disinformation. We will reveal and back up with evidence the attacks that are being carried out," Sejourne said on Saturday.
He also added that all EU countries are being targeted by Russian disinformation to destabilize and divide public opinion among the bloc’s member states.
On Monday, Poland’s Foreign Ministry chief Radoslaw Sikorski is traveling to Paris along with Prime Minister Donald Tusk. Sikorski is expected to meet his French and German counterparts Stephane Sejourne, and Annalena Baerbock to discuss increased support for Ukraine and the situation in the Middle East.
