China said on Tuesday it will turn away all meat shipped from Canada, just days before China and the United States sit down to work on settling a trade dispute that has also caught Canada in the crossfire.

Iran Press/Asia: China launched an investigation after inspections found residues of a feed additive not accepted by China in Canadian pork, the Chinese embassy in Canada said in a statement on its website.

That probe revealed as many as 188 “counterfeit” veterinary health certificates, the statement said, and the existence of “obvious safety loopholes,” Xinhua reported.

“In order to protect the safety of Chinese consumers, China has taken urgent preventive measures and requested the Canadian government to suspend the issuance of certificates for meat exported to China,” the statement said.

“We hope the Canadian side would attach great importance to this incident, complete the investigation as soon as possible and take effective measures to ensure the safety of food exported to China in a more responsible manner,” it added.

Canadian Agriculture Minister Marie-Claude Bibeau said in a statement that the Canadian Food and Inspection Agency (CFIA) had been working closely with industry and Chinese officials on the matter, and confirmed that it had found “inauthentic export certificates.”

“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.

Relations between China and Canada nosedived in December after Vancouver police detained Meng Wanzhou, the chief financial officer of Huawei Technologies Co, on a US arrest warrant. She denies any wrongdoing and Beijing is demanding her return.

After Meng’s arrest, China detained two Canadians and later formally charged them with espionage. Canada says the arrest of the two men was arbitrary. China has already blocked imports of Canadian canola seed.

On Tuesday, Meng’s lawyers urged Canada’s justice minister to withdraw extradition proceedings against Meng, but received no immediate response.

Though the issue is not on the official agenda, Canada’s Justice minister, David Lametti, is due to meet the US Attorney General William Barr in Washington on Wednesday.

A Canadian agriculture ministry notice said the Canadian Embassy in Beijing had been told Chinese customs agents would open all containers of Canadian meat and meat products, and that in some cases 100% of the contents would be inspected. 213/
