President Trump's threat to impose a 25% tariff on countries trading with Iran could jeopardize the trade truce with China, potentially raising tariffs on Chinese goods to over 70%. While Trump has not explicitly named China, experts suggest this move risks reigniting US-China friction, recalling past disputes like the Huawei case. Chinese officials and academics express skepticism about Trump's willingness to enact such tariffs, citing reduced Chinese trade with Iran and potential retaliation.
