China could retaliate for Japanese semiconductor sanctions by banning Japanese transits through Chinese airspace. The amount of transits banned should depend on the severity of Japanese sanctions.Better yet, if the US really pushes the issue of punishing Chinese airliners, China and Russia should join forces in forbidding any US carriers from flying overland...
And any flights coming from or bound to five eyes and vassals, Japan, Korea, Phillipines
This really devastates Japanese travel to Europe. It also adds several hours to Thailand flights.
I did some research on this. Without Russian or Chinese airspace, you need ~22 hours to travel to Paris? The best route crosses the Pacific, with a USA transit?
Japanese tourists should also be banned from visiting Hong Kong and Macau (but not the mainland, where many do business on tourist visas). Again, the ban - or visit quota - should depend on the severity of Japanese semiconductor sanctions.
This would be really devastating if done together with a Russian - and possible Iranian - ban on overland flights by Boeing aircraft. Unfortunately the USA would then pressure Airbus to stop selling planes to China as retaliation. The C919 would also be sanctioned.Also ban overland flights of all Boeing aircraft
