A lot of the European players that withdrew play the Euro Tour and the EPBF is obligated to follow the WPA's sanction so it make sense that they withdrew. What does not make sense is the powerplay between Matchroom and the WPA. There is no clash of dates for the Hanoi Open so it just political nonsense. I think someone mentioned that it’s the Asian Federation pushing for the ban and somehow the WPA has to give them deference since the event is being played in Asia. Not sure how the WPA can treat the Peri Open as sanctioned, but not the Hanoi Open ... unless the Asian Federation is pushing for a ban for the Hanoi Open only.
