"don't feel that expansionist"?!?
Sure, if you ignore their military actions and treaty violations in Tibet, Turkistan (Uyghurs), border conflicts around the Himalyas and India, Russia (border conflict), Korea, Vietnam, everywhere on the "9-dash line", Canada and the US (where they are putting up remote "police stations" to intimidate anyone expressing opinions they dislike)...
CCP has a highly consistent history of being as aggressive and untrustworthy as they can get away with. Anyone trusting them is a fool.
