Canadian Prime Minister Justin Trudeau said in a statement Saturday that he had asked for and received the resignation of John McCallum, the country's ambassador to China, CBC reports.

The big picture: The firing comes at an unusually tense time in China-Canada relations, with the detention of Huawei CFO Meng Wanzhou last month sparking what many believe to be retaliatory arrests of Canadian citizens by the Chinese government. Earlier this week, McCallum told reporters that it would be "great for Canada" if the U.S. dropped Meng's extradition request and listed arguments that could be used to bolster her case. McCallum was later forced to walk back the controversial comments.

Disney announced Tuesday that its most highly-anticipated blockbuster of the year, the live-action remake of "Mulan," is heading to Disney+ on Sept. 4 for consumers to purchase for a premium access fee of $29.99. The movie's theatrical debut had previously been delayed four times.

Why it matters: It's a huge blow to movie exhibitors across the country that were relying on the Disney hit to come exclusively to theaters for at least a few months before being made available to consumers at home via streaming.
