"I am not sure at this juncture whether it is going to be defense equipment support or whether it is going to be logistics support" <- This mean not committing Jap troops same like US now support Ukraine I see. Jap and China are still bitter over WWII past.
Not easy for Japan. Far and sea based.
Okinawa needs to be liberated too
Then Jippon be prepared to get bomb
The tone is clearly non commital. Taiwawa still having wet dreams?
