Trade negotiations between the US and Mexico have encountered an obstacle. A dispute over cheese names is the issue at hand. The US views names like parmesan and feta as generic, while the European Union believes they should only be used to label products from specific regions in Italy and Greece.

This disagreement is affecting the progress of the negotiations. The European Union's stance is that these names should be reserved for products from certain areas, implying that others should not use them. Further details on this development are available from the source, providing more insight into the dispute and its impact on trade negotiations.
