Canadian reactions to the announcement have ranged from regret to outrage, sprinkled with speculation that Beijing’s move might be related to the ongoing legal drama of Meng Wanzhou, the chief financial officer of Huawei who was arrested in Vancouver on a US warrant in December. Her extradition to the US is pending.

However, Agriculture Minister Marie-Claude Bibeau confirmed that the Canadian Food and Inspection Agency (CFIA) found “inauthentic export certificates” and was working closely with both the meat industry and Chinese officials to address the problem.

“CFIA is investigating this technical issue and has informed appropriate law enforcement agencies. This incident is specific to export certificates to China. Export certificates to other countries are not affected,” Bibeau said in the statement.

Prime Minister Justin Trudeau has sought help from US President Donald Trump, who is supposed to meet with Chinese President Xi Jinping at the upcoming G20 summit in Osaka, Japan and discuss trade relations that have been damaged by the ongoing tariff war.

Meanwhile, China is dealing with a shortage of pork due to the epidemic of African swine fever, which has killed millions of animals and driven up meat prices.
