  The $\gamma\gamma\to\pi\pi$ reactions are discussed. To describe those
processes, we include dipion continuum, resonances, high-energy pion-pion
rescatterings, $\rho$ meson exchange and pQCD Brodsky-Lepage mechanisms. The
cross section for the production of pion pairs in photon-photon collisions in
peripheral heavy ion collisions is calculated with the help of Equivalent
Photon Approximaption (EPA) in the impact parameter space. We show predictions
at $\sqrt{s_{NN}}=3.5$ TeV which could be measured e.g. by the ALICE
collaboration at the LHC.
