It's at most disrespectfull and at least ignorance. Of course, China is way ahead of everyone, but for South Korea, Japan and Taïwan vs France, Germany and Sweden, that's another story:
1- France has beaten Taïwan then Japan in WTTTC + '24 Olympics bronze medal match
2- Sweden has beaten Japan in the '24 Olympics semi final
So for Japan, they'd be at best the 3rd european nation, or even the 4th. Taïwan is near there too.
3- Do we really need to talk about Germany vs China classic finals all along the 2000's and 2010's era ? and still in 2022 WTTTC's semi final they've beaten South Korea.
4- Germany again has beaten Taïwan then Japan in the '20 Olympics
It's that simple: in any team competition in the World Championships or Olympics, there's never been any all asian final since the 2016 Olympics, so that will make 10 years next year in 2026 in London for the WTTTC.
