China warns against trade war as Trump threatens new tariffs

China has responded to President-elect Donald Trump's threat to impose new tariffs on imports from China, Canada, and Mexico. Trump announced he would introduce tariffs to combat drug trafficking and illegal immigration, stating they would remain until these issues are resolved. China's ambassador to the U.S. warned that a trade war would harm both countries. Premier Li Qiang also criticized protectionist measures, saying they disrupt global supply chains and increase costs. Despite previous agreements, tensions remain high, with little indication of a new trade deal. China has taken steps to address drug precursor exports, but the U.S. continues to express dissatisfaction with the results.
