Beijing: China on Tuesday warned the US and Canada that it will “take action” against them if they went ahead with the extradition of the CFO of Chinese telecom giant Huawei to America and accused both the countries of “abusing” their extradition treaty. Meng Wanzhou, Huawei’s global chief financial officer, was arrested in Canada on December 1 and faces extradition to the US, which alleges that she covered up her company’s links to a firm that tried to sell equipment to Iran despite sanctions linked to its nuclear programme. “China will take action in response to measures taken by the US,” Foreign Ministry spokesperson Hua Chunying warned.
