Foreign Ministry spokeswoman Hua Chunying said that China will take further responses if Washington proceeds with the formal request to extradite Meng.

David MacNaughton, Canada's ambassador to the US, said in an interview with Canada's Globe and Mail newspaper that Washington has informed Ottawa it will request Meng's extradition, but he did not say when the request will be made. The deadline for filing is Jan 30.

Meng was arrested in Vancouver at the request of the US on Dec 1 over alleged violations of US sanctions on Iran. A week later, Vice-Foreign Minister Le Yucheng summoned the Canadian and US ambassadors in Beijing, expressing strong protests over Meng's arrest.

At the daily news conference on Tuesday, Hua said that Canada and the US "arbitrarily abused" their bilateral extradition agreement in the case of Meng, and seriously infringed on the safety and legal rights of Chinese citizens.

China urged Canada to immediately release Meng and protect her legitimate rights, she said, adding that China also demands the US to correct its mistake, cancel its arrest warrant for Meng and not to make the formal extradition request.
