The Short Version
The claim is accurate for elephants but significantly mischaracterizes the status of rhinoceroses and tigers in Vietnam. Vietnam's Javan rhinoceros was declared extinct in-country in 2011, and extensive camera trap surveys from 2019–2023 detected zero wild tigers, indicating functional extirpation. Describing these species as currently "facing threats from habitat loss" and "classified as endangered" in Vietnam conflates global conservation status with in-country reality, where the more accurate designation is extinct or extirpated rather than endangered.
