A Chinese court upheld a Canadian man’s death sentence for drug smuggling, a day before judges are due to rule on the case of another Canadian accused of spying.

The court proceedings for the two come as lawyers in Canada representing the detained chief financial officer of telecoms giant Huawei make a final push to convince a court there not to extradite her to the United States, where she faces charges linked to violating sanctions.

Robert Schellenberg was arrested for drug smuggling in 2014 and jailed for 15 years in late 2018.

He appealed, but a court in the city of Dalian sentenced him to death in January 2019, a month after Huawei executive Meng Wanzhou was arrested at Vancouver International Airport on a warrant from the United States, charged with misleading HSBC Holdings about Huawei’s business dealings in Iran, potentially causing the bank to violate American economic sanctions.

Meng, who has said she is innocent, has been fighting her extradition from under house arrest in Vancouver.

The high court in the northeast province of Liaoning heard Schellenberg’s appeal against the death sentence in May last year.

It confirmed the verdict yesterday.

Speaking to reporters by telephone after attending the hearing, Canada’s ambassador to China, Dominic Barton, condemned the decision and called for China to grant clemency.

“It is not a coincidence that these are happening right now, while the case is going on in Vancouver,” Mr Barton said, referring to Schellenberg’s case and that of another Canadian, Michael Spavor.

China has rejected the suggestion the cases of the Canadians in China are linked to Meng’s case in Canada, although China has warned of unspecified consequences unless Meng was released. The Chinese foreign ministry did not immediately respond to a request for comment.

Businessman Mr Spavor was detained in China days after Meng’s arrest in Vancouver.

He was charged with espionage in June last year and went to trial in March.

Mr Barton said a court in the north-eastern city of Dandong, on a river bordering North Korea, is expected to announce a verdict on Mr Spavor today.
