I think Beijing didn't change at all. In fact, all of the evidence indicates that China is continuing on the same trajectory it has been on at least since Xi Jinping became general secretary in 2012. That is a trend toward deeper totalitarian governance, turning China into a police state with more egregious violations of human rights and more aggressive international behaviour.
For example, although China is perhaps not currently putting coercive pressure on Canada—although, as Ambassador Saint-Jacques noted, there are still barriers to pork and other products—it is aggressively bullying Japan, for example, and it continues to put pressure on other neighbours, such as the Philippines. No, it has not changed.
