The proposal of Oakes linking the pion mass and the strangeness-changing weak interactions in investigated in the (8,8) symmetry breaking of $\mathrm{SU}\mathrm{}\left(3\right)\mathrm{}\otimes \mathrm{SU}\mathrm{}\left(3\right)\mathrm{}$. This leads to a determination of the Cabibbo angle and the $\eta \to 3\pi$ decay rates which are in agreement with the earlier results in the $(3,\overline{3})\oplus (\overline{3},3)$ model. The connection between cancellations in the leading weakinteraction divergences and the Cabibbo angle, however, does not hold in the (8,8) scheme.
