China has declared a Canadian diplomat "persona non grata" and asked her to leave Shanghai.

The Chinese Communist Party (CCP) made the announcement as part of a reciprocal move after Canada made a similar decision towards a Chinese diplomat.

"On May 9, the Canadian government declared a diplomat of the Consulate-General of China in Toronto persona non grata," the CCP wrote in a Tuesday statement. "China strongly condemns and firmly opposes this and has lodged serious démarches and strong protest to Canada."

Chinese diplomat Zhao Wei was expelled from Canada on Monday after intelligence reports suspected him of intimidating the family of conservative Member of Parliament Michael Chong.

In retaliation for the expulsion, Consulate General of Canada in Shanghai Jennifer Lynn Lalonde has been asked to leave the country by May 13, according to the CCP.

"As a reciprocal countermeasure in reaction to Canada’s unscrupulous move, China decides to declare Jennifer Lynn Lalonde, consul of the Consulate General of Canada in Shanghai persona non grata, who has been asked to leave China no later than May 13," China's Ministry of Foreign Affairs wrote.
