The routes seem to be in countries that are not locking down as strictly.

Also the Asian routes tend to be routes that are not competitive by HSR for various reasons (Vietnam and Indonesia don't have any, Saudi Arabia's route is not connected via HSR); Bali and Jeju are separated from the other end of their trips by at least one large body of water with no land connection; Beijing, Shanghai, and the PRD are all way too far from each other on HSR to be competitive, as is Tokyo-Sapporo. That leaves Tokyo-Osaka, which is on the list primarily because even with HSR winning the mode share in that market the two metro areas are very large. (34m and 12m respectively, 21m if you count all of Kobe-Osaka-Kyoto)
