FILE - In this Feb. 26, 2016, file photo, Lacaune sheep, known for the famous French Roquefort cheese, are presented on the eve of the annual International Agriculture Fair, featuring farm animals, food and agriculture industry, in Paris. Japan and the European Union are hoping to reach an economic partnership agreement within days, countering the backlash against free trade by U.S. President Donald Trump. Their trade and agriculture ministers are due to meet in Tokyo on Friday, June 30, 2017, trying to forge a deal before the Group of 20 industrial nations meets next week in Germany. Local reports said a main point of disagreement was Japan's up to 40 percent tariffs on imported cheese. (AP Photo/Francois Mori, File)
