Chinese officials could reply that trust is not built with actions such as flirts with chinese secessionists, a blanket ban on chinese telco equipment manufacturers based on unsubstantiated allegiations of spying, weaponization of chipmaking gear, sanctions on chinese officials on made up genocide accusations and so on, but chinese politics and diplomacy is just too refined to lower themselves at the european clown level.
I understand the sentiment but what you actually don't want to do is give them an opportunity to repeat all their others lies.
IOW, don't give them an opening. Keep it anodyne. Just like corporate communications written in corporatese to an irate customer who's in the wrong...you don't apologize but no need to give them yet more opportunities to spew the rest of their lies.
Remember that we're all infested with thr Westoid mind-virus and so we think we must "stand up" and "give 'em a piece of our minds" but it's actually a delicate dance going on here, especially now with Gaza going on; you look reasonable by not getting bogged down in an argument.
It's like Maya Angelou's advice about "ignoring," so to speak, racist accusations (or as Eamon de Valera wrote, defeat the British Empire by ignoring it), which are hurled out not to engage in an discussion but to drain your energy responding to constant nonsense -- which, incidentally, careful observers have noted to be Trump's own m.o., nonstop b.s. like a missile swarm overwhelming the rational mind.
No, it's not satisfying but China needs to look like the Big Dog ignoring the little chihuahuas.
