TNo one that I know of (except Bruce Frantzis) is saying that Ueshiba trained with teachers of Chinese arts, but that doesn't mean that the influence isn't there.
What we're talking about is fairly specific, chance resemblance seems unlikely to me - especially given the increasingly large amount of information coming out.
The entire Japanese education system in Ueshiba's era was based around classical Chinese texts - I'm not sure why people find it so hard to accept that there was influence in all kinds of other areas as well.
So Ueshiba learned Chinese martial arts through some other means than training under a teacher?
Was it one of those special deals where you get the book, the video, and the black belt in the same package for $99.95??
