The European Union and Mercosur have reopened negotiations on a long-stalled free-trade agreement, as both sides look for ways to protect commerce from possible new US tariffs. The renewed talks mark another attempt to bridge years of political and economic differences between the two blocs.

Officials are seeking a deal that would expand market access across Europe and South America, while reducing uncertainty for exporters and investors. The timing of the talks underscores growing pressure on global trade flows as Washington signals the possibility of broader tariff action.

The agreement has faced repeated setbacks over environmental disputes, agricultural protections, and concerns from member states on both sides. Even so, the latest round suggests a fresh push to turn a politically sensitive accord into a working framework for trade.

For businesses tied to transatlantic and South American supply chains, the outcome could shape pricing, competition, and investment plans. Negotiators now face the challenge of converting renewed urgency into a deal that can survive domestic opposition and shifting trade tensions.
