(NAFB.com) – The National Farmers Union and Coldiretti issued a joint declaration and letter to President Donald Trump and European Commission President Ursula von der Leyen regarding trade. The groups are concerned about the ongoing trade dispute between the U.S. and the European Union. “Farmers on both sides of the Atlantic are feeling the stress and uncertainty from the threat of tariffs,” says NFU President Rob Larew. “Trade tensions will raise costs, disrupt supply chains, and restrict markets, causing farmers, consumers, and businesses to suffer.” The groups are asking leaders to begin negotiations as soon as possible to prevent further economic hardships for American and European farmers and communities. A statement from Coldiretti says the trade war puts all agricultural producers at risk and must be stopped before it causes further damage. Coldiretti is the leading organization representing agricultural entrepreneurs in Italy and Europe. NFU is the second-largest farm group in the U.S.
