03.09.2026
On 3 September, Deputy Prime Minister and Minister of Foreign Affairs Radosław Sikorski took part in a jubilee meeting of the Weimar Triangle foreign ministers. In Weimar, the chief diplomats of Poland, France, and Germany adopted a declaration to mark 35 years of building trilateral relations and confirm the countries' determination and willingness to cooperate further.
During trilateral consultations, the heads of diplomacy, Radosław Sikorski, Johann Wadephul, and Jean-Noël Barrot, discussed key aspects of European and transatlantic policy. The ministers spoke about defence cooperation as well as countering disinformation, FIMI (Foreign Information Manipulation and Interference), and hybrid threats. They also raised the situation in the Middle East, especially at the Strait of Hormuz. Additionally, the top diplomats noted the significant dynamic of meetings within the Weimar Triangle. They stressed the potential of trilateral ties, notably in European policy, security, and digital, scientific, and space cooperation.
In the declaration adopted during the jubilee meeting, the ministers reiterated readiness to jointly counter threats to Europe’s security resulting from Russia’s aggressive and imperial policy. Deputy Prime Minister Sikorski underlined that Poland has backed Minister Wadephul’s response and decisions in the wake of Russia’s aggressive acts in the territory of Germany, including the decisions to close Russia’s consulate in Bonn and the Russian House in Berlin.
We do not consent to the unpunished testing of our borders and to hostile acts taking place in our territories. We will not tolerate arson, railway attacks, and other provocations posing a risk to our citizens. Poland also summoned the Russian ambassador in order to express our firm opposition to the state-sponsored terrorism perpetrated by the Russian Federation. In fact, a problem of one of our allies is a problem of the entire NATO. Putin’s Russia remains one of the biggest security threats not just to Europe, but to the World Order altogether
- Deputy Prime Minister Sikorski said.
The top diplomats gave assurances of continued support to Ukraine in its fight. They agreed that there can be no secure Europe without sovereign Ukraine.
The partners confirmed their support for Poland’s position on increasing Europe’s competitiveness, including through building technological and economic independence, while maintaining partnership-based relations with the US. Also, the heads of diplomacies announced joint counteraction against disinformation and declared further enhanced cooperation.
Noting that regular trilateral political consultations are necessary, Deputy Prime Minister Radosław Sikorski invited his French and German counterparts to Poland for another meeting of the Weimar Triangle foreign ministers.

The Weimar Triangle format was set up in Weimar in 1991 by the foreign ministers of Poland, France, and Germany: Krzysztof Skubiszewski, Roland Dumas, and Hans-Dietrich Genscher. Its aim was to enhance cooperation between the three states and to overcome the divisions in Europe by integrating Poland into European and Euro-Atlantic structures.
Although the nature of that cooperation has evolved with time to keep up with the current challenges, the provisions of the 1991 Weimar Declaration on the Future of Europe have not lost their relevance. “We have a unique opportunity to further shape a new Europe, taking on shared responsibility in the spirit of human solidarity, conscious of our common destiny and drawing on the legacy of our shared values,” the ministers wrote. For 35 years now, the Weimar Triangle has proved its effectiveness through overcoming divides, building trust, and remaining open to dialogue.
