Anyways: one such report, about the conference, is via MEMRI. MEMRI is itself not really all that trustworthy! I would steer away from any analytical results! But this piece is largely direct quotes. Maybe they're fabricating them. Seems a little unlikely, though?

Notably, a bunch of more mainstream sources corroborated this report (just Google for the name of the conference). I think it's very likely to be legitimate.
