There are many senses for the subject and the object of the statement.
Seemingly "rhetoric" implies here "the rules and techniques of effective 
manipulation of natural languages", not  empty talks or using pleasing 
language.
Also there are many types and sorts of communication, from document and 
publication to language to signal and sign to written communication to 
visual communication and to psychic communication".
I suggest you meant to say that "Communication of any kind is founded on 
semantics", dealing with the content and substance of any communication.
