Switzerland is holding a popular vote on a trade agreement with Indonesia, which could impact the country's agreement with Mercosur. The controversy surrounds Indonesia's environmental policy, particularly the production of palm oil. To approve the agreement, the Swiss government has added conditions for preferential access of palm oil in the Swiss market. However, environmental groups are dissatisfied with these clauses and the referendum's outcome could impact the Mercosur agreement. The debate also raises concerns about the Brazilian president's negative image in Europe.
