Only 2 Polish vodkas among protected products in Mercosur. Why?

It does not include oscypek, Korycin cheese, obwarzanek krakowski or kiełbasa lisiecka. The list of names of Polish products to be protected from counterfeiting in the markets of Mecosur countries is exceptionally short, but advanced in interest. But interestingly, it was not created now, and the astonishment of any politicians on the right seems belated.
