European Union leaders expressed frustration with Council President António Costa after he opened a diplomatic channel with Russia without consulting member states [1].

This rift highlights a significant struggle over the EU's unified foreign policy. If the Council President acts unilaterally on high-stakes diplomacy, it could undermine the coordinated sanctions and political pressure the bloc has maintained against the Kremlin [1, 4].

The tension peaked during the EU Council summit in Brussels on Thursday [2]. French President Emmanuel Macron and German Chancellor Friedrich Merz led the opposition to Costa's plan [1, 4]. Both leaders rejected the decision to establish these communications, citing a lack of prior consultation [1, 4].

Costa defended the surprise decision to open the channel [2]. He said that maintaining a line of communication is necessary for diplomatic flexibility. However, critics within the council said that such moves bypass the collective decision-making process essential to the union's stability [1, 3].

The disagreement centers on whether the Council President has the authority to initiate contact with Russia independently. Macron and Merz said that the move contradicts the EU's current stance on engaging with the Russian leadership [4]. The dispute has deepened existing splits within the council regarding how to handle the conflict in Ukraine, and the broader relationship with Moscow [1].

Leaders at the summit said that a fragmented approach to Russia would weaken the EU's bargaining power on the global stage [1, 4]. While Costa maintains the necessity of the channel, the pushback from France and Germany suggests a lack of consensus for such a strategy to succeed.

“EU leaders expressed frustration with Council President António Costa after he opened a diplomatic channel with Russia.”

The friction between António Costa and the EU's most powerful member states reflects a systemic tension between the executive functions of the Council Presidency and the sovereignty of individual nations. By bypassing consultation, Costa risked alienating the 'Franco-German engine' that typically drives EU policy. This incident suggests that despite the need for diplomatic agility, the EU remains strictly committed to a consensus-based approach when dealing with Russia to avoid appearing divided.
