Overview

  • The European Commission confirmed the May 1 launch after receiving a note verbale from Paraguay signaling approval.
  • Trade provisions will apply on a temporary basis and could be halted if the European Court of Justice finds the move unlawful or if Parliament ultimately withholds consent.
  • Uruguay, Brazil, Paraguay and Argentina have ratified the pact, while Bolivia did not take part in negotiations but could join later.
  • The agreement links more than 700 million people and roughly a quarter of global GDP, removing tariffs on over 90% of trade between the blocs.
  • Opposition from farmers, environmental groups and leaders including France’s Emmanuel Macron persists, even as EU officials frame the deal as key to resilience and growth.
