Day one of the World Meat Congress was overshadowed by US President Donald Trump's announcement of trade sanctions on Canada, Mexico and the EU. The sanctions are to protect national security. According to the US government, they will ensure that American steel and alloy companies remain in business to provide materials of national importance (eg tanks) and other materials if the US found itself at war in the future. The EU shipped €5.3bn of steel products and €1bn of aluminium products to America in 2017.
