TORONTO (AP) — Canada’s ambassador to China says a top Chinese executive has a strong case to avoid extradition to the United States.

Ambassador John McCallum told Chinese language media in Markham, Ontario on Tuesday that Huawei executive Meng Wanzhou has “quite good arguments” including “political involvement by comments from Donald Trump on her case.”

Canada arrested the daughter of Huawei’s founder at the request of the U.S. on Dec. 1. She is wanted on fraud charges that she misled banks about the company’s business dealings in Iran.

Trump said last month he might abandon the Meng case in pursuit of a trade deal with Beijing. That led some to suggest the case has been politicized and the U.S. is loosening its commitment to the rule of law and an independent judiciary.
