The European Commission has moved to accelerate the EU–Mercosur agreement by opting for provisional application of its trade provisions, opening a new confrontation with France and reviving a wider dispute over how far Brussels can advance a major commercial pact before the full ratification process is complete.
The decision means parts of the agreement can begin taking effect before the European Parliament has given final consent and before all national ratifications required for the broader partnership agreement have been completed.
The agreement links the European Union with the Mercosur states of Argentina, Brazil, Paraguay and Uruguay. Negotiations began in 1999 and were politically concluded on 6 December 2024. The package was then divided into two legally distinct instruments: the EU–Mercosur Partnership Agreement, covering political dialogue, cooperation and trade, and an interim Trade Agreement covering trade and investment commitments designed to apply ahead of the full partnership accord. On 9 January 2026, the Council authorised signature of both texts, and they were formally signed on 17 January in Paraguay.
The Commission’s latest step concerns that interim trade track. According to Reuters, Brussels decided on Friday to proceed with provisional application once Mercosur ratifications made that route possible. Argentina and Uruguay ratified the accord on Thursday, prompting Commission President Ursula von der Leyen to declare that the EU would now move ahead. The practical effect is that tariff reductions and other trade measures may begin before the agreement completes the full European legislative journey. Brussels argues that the move is necessary if the EU is to secure commercial and strategic advantage in a more protectionist global environment.
That rationale has found support in capitals such as Berlin and Madrid. Supporters of the deal argue that the agreement would help offset business lost to US tariffs, expand market access for European exporters and reduce dependence on China in sectors linked to critical raw materials and industrial supply chains. The Council has described the deal as creating the world’s largest free-trade area, covering more than 700 million people, while EU–Mercosur trade in goods was worth more than €111 billion in 2024, with services trade exceeding €42 billion in 2023. Reuters has also reported that the agreement could remove around €4 billion in duties on EU exports.
Yet the speed of the Commission’s move has sharpened opposition in France, where the Mercosur file has become politically charged well beyond normal trade policy arguments. President Emmanuel Macron described the decision as “a bad surprise” and “disrespectful”, saying the Commission was moving in a way that disregarded both French concerns and the position of the European Parliament. France, the EU’s largest agricultural producer, has consistently argued that the agreement would expose European farmers to increased imports of cheaper South American beef, sugar and poultry, while domestic producers remain bound by stricter regulatory and environmental requirements. French farming protests earlier this year showed how rapidly the issue can move from trade diplomacy into national politics.

The French objection is not only about agriculture. It is also about institutional process. Paris and a number of critics in Parliament argue that splitting the agreement into separate legal instruments allows the Commission and supportive member states to advance the trade pillar while postponing the harder political and constitutional questions attached to the broader partnership. On 21 January, the European Parliament voted by 334 votes to 324 to ask the European Court of Justice to examine whether the EU–Mercosur agreements conform with the Treaties. Parliament said it would continue examining the texts, but that its final consent vote would come only after the Court’s opinion. That legal review could delay final ratification even if provisional application proceeds.

The democratic argument is therefore likely to become central in the coming weeks. Critics say Brussels is effectively allowing a substantial part of one of the EU’s biggest trade accords to start operating before the normal chain of parliamentary and national scrutiny has run its course. Supporters answer that provisional application is a recognised feature of EU external agreements and that the interim trade agreement was explicitly designed to deliver negotiated economic benefits earlier than the full partnership treaty. The Council’s own description of the pact makes that intention clear: the interim agreement is meant to function as a stand-alone arrangement until the full partnership enters into force.
This leaves the Mercosur deal at the intersection of three separate European debates. The first concerns trade strategy: whether the EU should push harder for large external agreements as the United States turns more protectionist and competition with China intensifies. The second concerns agriculture, market access and the balance between open trade and domestic protection. The third concerns governance inside the Union itself: who decides, on what legal basis, and how much room the Commission has to move ahead when political consent remains incomplete. Brussels may have accelerated the deal, but it has also ensured that the fight over Mercosur will now be about the EU’s constitutional politics as much as its trade policy.
