Canadian Prime Minister Justin Trudeau expressed "extreme concern" after a Chinese court sentenced a Canadian man to death in a retrial ordered not long after the arrest in Vancouver of a Chinese technology executive.
It complicates an ongoing standoff over the arrest of Huawei Technologies' chief financial officer on US charges and the subsequent detention in China of two Canadians.
Trudeau suggested that he sees Robert Lloyd Schellenberg's new sentence as a political move. "It is of extreme concern to us as a government - as it should be to all our international friends and allies - that China has chosen to begin to arbitrarily apply a death penalty."
The arrest of Huawei's Meng Wanzhou has left Canada caught in the middle of a broader conflict between the US and China and sent Canada-China ties to new lows.
The standoff started with Meng's December 1 arrest in Canada on US charges related to alleged violations of Iran sanctions. Days later, Chinese authorities detained Michael Kovrig and Michael Spavor on suspicion of endangering national security.
