Canadian Prime Minister Justin Trudeau said Thursday that China doesn’t get that Canada has an independent judicial system and reiterated his charge that Beijing imprisoned two Canadians in retaliation for the arrest of a top Huawei executive.

Trudeau said Canada will continue to press Beijing to release Michael Kovrig and Michael Spavor, both detained since December 2018 following Canada’s arrest of Meng Wanzhou, a Chinese Huawei offical and the daughter of the company’s founder.

Canadian police detained Meng in Vancouver on a U.S. extradition request nine days before Kovrig and Spavor were arrested.
