Canada's relationship with China also deteriorated under Justin Trudeau, chiefly as a result of the Meng Wanzhou affair. Since Meng Wanzhou's arrest at the Vancouver airport in December 2018, two Canadians (Michael Spavor and Michael Kovrig) are held in custody in China. Both countries have requested the release of their nationals, which they see as political prisoners. Justin Trudeau claims he does not have the authority to free Meng Wanzhou, as his policy is to respect Canada's extradition treaty with the United States.
