Hi Zhou,
CDISC SDTM CT codelist (ETHINC) is designed for FDA. So, for FDA submissions, you have to use this codelist and keep additional more granular information like “Ethnicity as Collected” in SUPPDM dataset if needed.
For other regulatory agencies, I would recommend to contact them for clarification. For example, (ETHINCC) codelist includes 56 terms for Chinese-specific ethnicity which may be valuable for NMPA review.
Kind Regards,
Sergiy
P.S. However, I am not sure about sense of English terms for NMPA submission.
