American President Donald Trump warned that China would face a 50% tariff if it transfers weapons to Iran. He added that he doubted Beijing would do this, despite American intelligence indicating there were such plans. "I hear news that China is supplying hypersonic missiles, which are called hypersonic missiles, anti-aircraft missiles. I doubt they would do this, because I have a relationship and I think they wouldn't do this," he told Fox News on the program "Sunday Morning Futures with Maria Bartiromo." He expressed that perhaps China did it initially, but emphasized that he doesn't think they will do it anymore. "But if we catch them doing this, they get a 50% tariff, which is a staggering amount," said Trump. American intelligence indicates that China is preparing to deliver new air defense systems to Iran within the next few weeks, according to three people familiar with the latest intelligence assessments.
