US press secretary's China toilet remark draws pointed Chinese invitation

New White House press secretary Katie Zacharia, in her fifth day on the job, triggered a diplomatic spat by saying China 'doesn't even have proper toilets' in an interview. Chinese foreign ministry spokeswoman Mao Ning responded with a smiling, brief invitation for Zacharia to visit China, a contrast in rhetorical styles that underscores ongoing US-China friction. The incident is a minor diplomatic flashpoint, with the Chinese response signaling a willingness to counter US criticism while maintaining a composed public posture.
