"I was told that they will continue [the US Justice Department]," said David MacNaughton, Canada's ambassador to the United States, to CNN on Monday. "We have no indication that this will not be the case."
The arrest of Huawei Chairman Meng Wanzhou has weighed on relations between Canada, the US and China. It also raised the question of how far the US government can proceed in its efforts to tackle Huawei, which is considered a national security threat.
The Chinese Foreign Ministry reiterated its demand to release Meng and claimed that the United States and Canada had abused their extradition treaty.

Meng, the daughter of Huawei's founder, was arrested last month in Vancouver by Canadian authorities on behalf of the United States. The US government claims it helped Huawei circumvent US sanctions against Iran.

. Meng and Huawei have denied any wrongdoing.
Canada claims that Meng's arrest has taken place is a legal matter, and the country is abiding by national laws and international obligations.
This position was undermined by US President Donald Trump, who suggested last month that he might intervene in the legal saga if he sought to trade with China.
MacNaughton said he had "asked for clarification that this is a legal matter and not a chip in a trade dispute".
"Canadians are arrested and one is sentenced to death," he added. "That's serious stuff."
Since Meng's arrest, China has arrested two Canadians on suspicion of "activities jeopardizing China's national security." Last week, another Canadian was sentenced to death after a drug trafficking court convicted him.
MacNaughton made comments on the case for the first time in an interview with the Canadian newspaper The Globe and Mail.
