We summarize the results we obtained for the partial decay widths of φ(2170) into two-body final states formed by a K and a Kaonic resonance, like $K(1460)$, K₁(1270), as well as to final states constituted by a φ and an η/η^ mesons. The results obtained are compared with the values extracted from experimental data on the corresponding branching ratios, which were determined by the BESIII collaboration. A reasonable agreement is found, which together with the previous reproduction of the mass, width, and cross section for the process e⁺ e⁻→ φ f₀ strongly indicates the molecular nature of φ(2170) as a φ K K system.
