The result was delete. No reliable, secondary sources about this event are referenced or even available. A future article could be created if those reliable, secondary sources about the event itself - not simply papers presented at the conference - can be found and provided.

I came across this via speedy as a A7, but the big issue was that it had been removed by a user other than the original creator. I do have serious doubts about the symposium's notability and I do think that there is some COI involved, as one of the user's names seems to be the same as the name of the author of this book that is a list of the proceedings of the symposium. However since this is a Russian event, there is the possibility of sources in Russian so I'd prefer this go through AfD, especially since I'm not sure that re-tagging an article with a speedy tag is really something applicable here.

There are some reasons why the conference is important on the talk page of the original article. I don't think one need to copy it here. I also want to add some observations:
