dont know who the "authorities" are & things may have changed but my Intl DL purchased in June 23 does not include Vietnam. Friends travelling there this year had the same.
Beware motorcycle riding in Vietnam. You can not get an international driver's licence for Viet. Could have serious ramifications in an accident for your travel insurance
