US President Donald Trump claimed to have persuaded French President Emmanuel Macron to raise drug prices in Europe, reportedly threatening a 25 percent tariff on all French products exported to the US[3]. However, France rejected Trump's claims and did not recognize his demands to increase drug prices[3]. The French Ministry of Foreign Affairs emphasized that threats of tariffs to influence foreign policy are unacceptable and ineffective[1]. Since the summer, when Washington reached an agreement with the European Union on 15 percent tariffs on most European exports, no presidential decision has been issued in France to change drug prices[3]. French Economy Minister Annie Genevard warned that the introduction of tariffs could also harm the American economy, including American farmers and industrialists[6]. Drug tariffs could disrupt complex supply chains and cause a shortage of cheap generics in the US market[8].
