Trudeau thanked Trump in a phone call on Saturday for the United States’ support in “seeking the immediate release of the two Canadian citizens arbitrarily detained by China,” the prime minister’s office said in a readout statement of the call.
The statements did not give more information. The White House had no immediate comment on further details about the call.
The relations between Canada and China have since been tense.
The US’ own tensions with China have also increased recently over the handling of the coronavirus outbreak, the ongoing trade war between the two countries, China’s imposition of a national security law on Hong Kong and the subsequent end to Hong Kong’s special status under US law by Trump.
The Trump administration has restricted technology exports to Chinese companies, notably Huawei, citing national security risks. The company has denied such charges.
