Thousands protest as EU leaders clash over trade pact farmers fear will flood Europe with cheaper South American goods.
Published On 18 Dec 2025
Hundreds of tractors have clogged the streets of Brussels as farmers converged on the Belgian capital to protest against the contentious trade agreement between the European Union and South American nations they say will destroy their livelihoods.
The demonstrations erupted on Thursday as EU leaders gathered for a summit where the fate of the Mercosur deal hung in the balance. More than 150 tractors blocked central Brussels, with an estimated 10,000 protesters expected in the European quarter, according to farm lobby Copa-Cogeca.

It made for a twin-tracked day of febrile tension outside and inside at the EU summit as leaders were perhaps more focused on a vote to determine whether they are able to use nearly $200bn in frozen Russian assets to support Ukraine over the next two years.
Outside the gilded halls on the streets, farmers hurled potatoes and eggs at police, set off fireworks and firecrackers, and brought traffic to a standstill.
Authorities responded with tear gas and water cannon, setting up roadblocks and closing tunnels around the city. One tractor displayed a sign reading: “Why import sugar from the other side of the world when we produce the best right here?”
“We’re here to say no to Mercosur,” Belgian dairy farmer Maxime Mabille said, accusing European Commission chief Ursula von der Leyen of trying to “force the deal through” like “Europe has become a dictatorship”.
Protesters fear an influx of cheaper agricultural products from Brazil and neighbouring countries would undercut European producers. Their concerns centre on beef, sugar, rice, honey and soya beans from South American competitors facing less stringent regulations, particularly on pesticides banned in the EU.
“We’ve been protesting since 2024 in France, in Belgium and elsewhere,” said Florian Poncelet of Belgian farm union FJA. “We’d like to be finally listened to.”
France and Italy now lead opposition to the deal, with President Emmanuel Macron declaring that “we are not ready” and the agreement “cannot be signed” in its current form.
France has coordinated with Poland, Belgium, Austria and Ireland to force a postponement, giving critics sufficient votes within the European Council to potentially block the pact.
However, Germany and Spain are pushing hard for approval. German Chancellor Friedrich Merz warned that decisions “must be made now” if the EU wants to “remain credible in global trade policy”, while Spanish Prime Minister Pedro Sanchez argued the deal would give Europe “geo-economic and geopolitical weight” against adversaries.
The agreement, 25 years in the making, would create the world’s largest free-trade area covering 780 million people and a quarter of global gross domestic product (GDP).
Supporters say it offers a counterweight to China and would boost European exports of vehicles, machinery and wines amid rising US tariffs.
Despite provisional safeguards negotiated on Wednesday to cap sensitive imports, opposition has intensified. Von der Leyen remains determined to travel to Brazil this weekend to sign the deal, but needs backing from at least two-thirds of EU nations.
Brazil’s President Luiz Inacio Lula da Silva issued an ultimatum on Wednesday, warning that Saturday represents a “now or never” moment, adding that “Brazil won’t make any more agreements while I’m president” if the deal fails.
