The verdict sentencing Canadian Michael Spavor to 11 years in prison
was delivered in a courtroom in the northeastern Chinese city of Dandong.
The city had been home to the businessman who organized tours to North Korea
until he was detained in December 2018 and charged with sharing state secrets.
Former Canadian diplomat Michael Kovrig was also arrested and charged with spying.
Both men were trialed in March after more than two years in detention.
The Chinese court sentenced Michael Spavor to 11 years in prison and ordered his deportation, but it's unclear when that would happen.
Canadian officials say it's most likely after the jail term he served, but some analysts say it could be sooner.
The verdict follows the upholding of the death sentence of another Canadian, Robert Schellenberg, on Tuesday.
He was jailed in China in 2014 for drug smuggling.
It's unclear when the court will give its decision on Michael Kovrig.
Michael Spavor has 10 days to appeal his sentence, but the chances of overturning the ruling are unlikely.
