Morita equivalence for C*-algebras with the weak Banach-Saks property

Let two C*-algebras A and B be Morita equivalent and let X be an A-B-imptimitivity bimodule. Consider the following conditions: (1) A has the weak Banach-Saks property; (2) B has the weak Banach-Saks property; (3) X has the uniform weak Banach-Saks property. Then we show that (1) and (2) are equivalent and (2) implies (3), and that if A or B is unital, then conditions (1) to (3) are equivalent.
