Ryszard Czarnecki is a Polish politician and a member of the European Parliament from Poland.
Translate his tweet to English: "Literally minutes away from us the decision of FIVB - the world volleyball federation who will be the organizer of the women's world championship in 2022. We strongly believe that Poland and the Netherlands!"
He did not officially confirm that Poland and Netherland will host WCH 2022 although he believed these two cities have a good chance. His tweet was post on Nov 16th, 2018. It's kind of early.
We may have to wait the formal announcement from FIVB.
So this is a confirmation of joint offer of Poland and the Netherlands. Probably the Netherlands made a bid and then they were looking for some other country interested in hosting part of the competition and then Poland agreed and that is the reason of the delay in announcement. Fingers crossed that it will become reality
Beside being a politician, Czarnecki is also vice-president in PZPS (polish volleyball federation).
