Perhaps not...time will tell. When I see that pic published in an article with the tatment by the PRC official...IMHO, that gives it additional weight.
If that official did not know that that particular picture would be published in the article, then all bets are off.
Wait, I'm confused -- what statement by which PRC official?
That picture is from some sort of academic study, and unrelated to any statement by any Chinese official. Am I misunderstanding you or might you be mixing two separate events up?
This is the full page of the particular study that the picture is from, and is quite a few years old (nearly four years old now):
