Andrey, thanks for the info!
There is an understanding that there is a negotiation process, so far no more.
With regards to the partner, I absolutely do not understand the interest of the organizers of the exhibition, to pay for accommodation, meals, transfers, excursions, etc. DC and members of their families, for me it is kind of fiction (I could be wrong
)))
Regarding the invitation of guests, we invite someone to BAT to the exhibition, or to US at the conference ...? These are completely different things.
And according to the MEETING in Krasnodar, this has nothing to do with the conference, and as I understand it, it can be positioned as a meeting of colleagues and friends and can be held at any time, which will be convenient for the participants.
In any case, there is an understanding of the ongoing process in our organization.
