  We have identified the decay modes of the $D_s^+ \to \pi^+ K^+ K^- , \pi^+
K_s^0 K_s^0$ reactions producing two vector mesons and one pseudoscalar. The
posterior vector-vector interaction generates two resonances that we associate
to the $f_0(1710)$ and the $a_0(1710)$ recently claimed. We find two acceptable
scenarios that give results for the ratio of the branching ratios of these two
reactions in agreement with experiment. With these two scenarios we make
predictions for the branching ratios of the $D_s^+ \to \pi^0 K^+ K_s^0$
reaction, finding values within the range of $(2.0 \pm 0.7)\times 10^{-3}$.
Comparison of these predictions with coming experimental results on that latter
reaction will be very most useful to deepen our understanding on the nature of
these two resonances.
