We discuss an extension of the hypothesis of asymptotic level realization of SU(3) to a certain chiral SU(3) \ensuremath{\bigotimes} SU(3) charge-charge-density algebra, which is applied to the ground-state mesons. It produces interesting dynamical constraints for various couplings of the ground-state mesons which, among other results, permit us to compute the rate of the $\ensuremath{\varphi}\ensuremath{\rightarrow}\ensuremath{\pi}\ensuremath{\gamma}$ decay. This decay is forbidden in this formulation if the masses of $\ensuremath{\rho}$ and $\ensuremath{\omega}$ are degenerate.
