On June 30, a summit of Mercosur (the Southern Common Market) is being held in Asunción, the capital of Paraguay. According to reports, the rotating pro tempore presidency passes to Uruguay at this meeting, which becomes the first formal leader-level discussion since the comprehensive EU-Mercosur agreement entered provisional application on May 1. A practical question, how to share the benefits of tariff cuts within the bloc, and a political one, how to reconcile differences in tone among member states, are piling up at the same time.
The "Next Phase" of the EU Deal
From its formal signing in January to the start of provisional application in May, the EU-Mercosur agreement has drawn attention at each milestone. But now that trade has actually begun to move, the center of attention has shifted to practical details: which goods will see tariffs fall over how many years, and at what point agricultural safeguards can be triggered.
According to reports, one of the main items at this summit is how to allocate, among the four Mercosur countries, the import quotas set with the EU for farm products, automobiles, electrical equipment, and more. Because Brazil is overwhelmingly the largest exporter, there are moments where its interests do not align with those of Argentina, Paraguay, and Uruguay. The four countries, which spoke with "one voice" in negotiations with the EU, have now entered a phase where they hold together on the outside while competing for their share on the inside.
Paraguay, the "Quiet Overachiever"
Paraguay, the host this time, is among the smallest members of Mercosur in both population and economic size. Yet its real GDP growth for 2025 is reported to have reached 6.6%, an outstanding pace even by South American standards. S&P granted it an investment-grade rating in December 2025, and confidence in its currency and public finances has risen.
This growth is underpinned by agricultural exports such as soybeans and beef, and by manufacturing that builds on abundant hydropower. The country holds two giant dams, Itaipú and Yacyretá, and its structure of earning steady dollar income by selling electricity to neighboring Brazil remains intact. From the standpoint of energy security, its profile among neighbors is rising as well. Reports also say the Asunción stock exchange introduced an international trading system in early 2026 and has begun building ties with overseas custodians.
A Geopolitics of Mixed Left and Right
Mercosur now finds itself in a delicate situation with left- and right-leaning governments mixed together. Argentina (the Milei government) has made its pro-U.S. stance clear, and Uruguay maintains a conservative posture. Brazil (the Lula government), which hands off the presidency, is center-left and emphasizes multilateral cooperation within the bloc. On advancing the EU deal everyone shares an interest, but on other policies, migration, the environment, security, the bloc's footing is easily thrown off.
My Perspective
Whether the Asunción summit can settle the practical details of quota allocation on the spot is one question. But I see the real measure of this meeting elsewhere: whether all sides can value the limited progress of "provisional application" and reaffirm their will toward full ratification. A framework for regional integration produces outward fruit in the form of collective bargaining power, while it inevitably carries inward friction over how to divide that fruit among members. Mercosur has entered exactly that stage.
What I find intriguing on top of this is that the smallest member, Paraguay, is gaining a larger presence within the bloc. A small country, often buffeted by the logic of larger ones, is steadily building growth and credibility at its own pace, standing on the firm comparative advantages of energy and agriculture. The very fact that all four countries sit equally at the table to share the benefits of the agreement is, I think, the current measure of Mercosur's strength, and a foothold for negotiation even for its smaller members.
Glossary

The very fact that all four countries sit equally at the table to share the deal's benefits is the current measure of Mercosur's strength.
