In an interview with the New York Times, Donald Trump said that Akie Abe, wife of Japan Prime Minister Abe, didn't even say "hello" to him at the G20 dinner because she doesn't speak English:
So, I was seated next to the wife of Prime Minister Abe [Shinzo Abe of Japan], who I think is a terrific guy, and she’s a terrific woman, but doesn’t speak English.
HABERMAN: Like, nothing, right? Like zero?
TRUMP: Like, not “hello.”
HABERMAN: That must make for an awkward seating.
TRUMP: Well, it’s hard, because you know, you’re sitting there for——
HABERMAN: Hours.
TRUMP: So the dinner was probably an hour and 45 minutes.
But a number of videos have surfaced showing that Mrs. Abe has a pretty great command of the English language. So, why wouldn't she speak with Trump?
