Former US President Donald Trump recently announced that he will impose tariffs on countries that have treated the US unfairly. This move is aimed at responding to potential trade barriers or unfair competitive practices by other countries. Trump emphasized that this action is for the protection of US economic interests and job opportunities. He stated that the US would no longer tolerate actions by countries imposing restrictions on US exports or damaging US business interests through unfair trade practices. This decision has drawn widespread attention in the global trade sector and is expected to further increase the uncertainty in international trade relations.
