No winners in a tariff war: China on Trump's 50% tariff threat over weapon supply to Iran

China has rejected reports claiming it's preparing to supply weapons to Iran amid the West Asia war, terming them "groundless smears and malicious associations". Foreign Ministry spokesperson Guo Jiakun also responded to US President Donald Trump's "staggering" 50% tariff if China is found to be doing so, saying, "There can be no winners in a tariff war."
