Brazilian President Luiz Inacio Lula da Silva said on Wednesday he hoped a trade deal between the European Union and the South American Mercosur bloc would be signed by the end of this year, even as it faced opposition,

The Carrefour CEO's comments over an EU-Mercosur trade deal caused disruption to supplies of meat to Brazil stores.

The French giant has come out in support of farmers to block the prospect of meat imports from the South America bloc.

The EU and the South American trade bloc Mercosur are working to finalize a trade deal that has been in negotiation for over 20 years.

Poland opposes the EU-Mercosur free trade deal with South American countries in its current form, the prime minister said on Tuesday, joining France in standing against an agreement European farmers say will expose them to unfair competition.

Brazilian President Luiz Inacio Lula da Silva expressed optimism for finalizing a trade deal between the EU and the Mercosur bloc by year-end. Despite French opposition, negotiations progress with European Commission President Ursula von der Leyen leading efforts.

The deal has been 25 years in the making and it aims to create one of the largest free trade zones in the world - but farmers in Europe are heavily opposed to sealing it, saying that they cannot compete with South American livestock producers.
