Anime Festival Asia is (I think) the largest convention in Southeast Asia. Their main convention is in Singapore but have done other satellite ones around the region.
The Singapore con was pretty recent in November 2023 and it even had a Hololive meet event. Even still, I think this will probably be a huge event as I don’t think AFA has done anything outside Singapore since before the pandemic.
I’m sure
@Faceless Waifu could probably expand on how relevant this convention is.
