Canada has formally asked China for clemency in the case of Canadian Robert Lloyd Schellenberg, who was sentenced to death for drug smuggling by a Dalian court Monday, AFP reported.

“We have already spoken with China’s ambassador to Canada and requested clemency,” Canada’s Foreign Minister Chrystia Freeland said Tuesday, according to AFP.

Canada issued an advisory for its citizens traveling to China Monday, warning of potential “arbitrary enforcement of local laws,” just hours after China announced the verdict on Schellenberg. Schellenberg’s case is the latest diplomatic tussle between the two countries after the December arrest in Vancouver of Meng Wanzhou, chief financial officer of Chinese telecommunications company Huawei.
