The implication of chiral symmetry for the pion-induced dissociation of the J/{psi} is examined in detail. It is shown how the low-energy dynamics of pions, constrained by chiral symmetry, affect the dissociation cross section. The derived soft-pion theorem is then integrated into a Lagrangian model that includes also abnormal parity content and chiral-symmetric form factors. Dissociation by the {rho} meson is also considered.
