China released names of only those dead who recieved gallantry or other awards.Dug up stuff from Jun 23 2020.
Was he one of those killed in the Galwan clash specifically?
China released the names and publicized the contributions way later (few months ago). That twitter post has been tagged to Global times and the editor so they'd have known about it in Jun, 2020 itself.
If hiding was their intention, they'd have included his name in the final release made later.
The fact that he wasn't then would only mean that he wasn't a direct casualty of the fight.
But then again, let's give some merit - one down 40 more to go.
This guy did not recieve any award so they did not bother releasing his name in Feb 2021 PR.
