Could China limit Japanese airlines’ access to its airspace as ties sour?
Pilots say such a move would mark a major escalation of retribution for Japanese PM’s remarks on Taiwan

Japanese airlines’ lucrative European routes could become a victim of simmering tensions between China and Japan because access to airspace is a potential lever for Beijing, aviation professionals have warned.
However, they said outright closure of Chinese airspace remained unlikely because it would snarl regional air traffic and embroil Chinese carriers.
Aviation observers in China have recently discussed the likelihood of Beijing restricting or forbidding Japanese carriers from overflying the country as a new retributory tactic in the wake of mass Japan-bound flight cancellations.
Widespread flight cancellations and official advisories against visiting Japan have been among Beijing’s retaliatory measures so far, with pilots warning that curtailment of access to Chinese airspace would mark a major escalation.
“If China weaponises airspace access, it will be more consequential than cancelling flights because the busy Japan-Europe air traffic and cargo will take a hit, with some routes facing suspension,” said a European pilot with a leading budget carrier in Shanghai.
“This is a card in Beijing’s hand and a vulnerability for Japan as the latter’s airlines will be squeezed.”
