China warns US over sanctions on oil firm

China's Ministry of Foreign Affairs has issued a formal warning to the United States over its imposition of unilateral sanctions. Official spokesperson Lin Jian criticized recent US sanctions against a Chinese oil refinery, which were levied under the pretext of the firm's ties with Iran. He urged Washington to abandon its "wrong approach" to sanctions and the practice of extraterritorial jurisdiction. The statement reflects escalating diplomatic tensions over US secondary sanctions targeting Chinese entities.
