  The implications of the first AMS-02 $\bar p/p$ data for the propagation of
cosmic rays and the properties of dark matter (DM) are discussed. Using various
diffusive re-acceleration (DR) propagation models, one can derive very
conservative upper limits on the DM annihilation cross sections. The limits
turned out to be compatible with that from the Ferm-LAT gamma-ray data on the
dwarf spheroidal satellite galaxies. The flattening of the $\bar p/p$ spectrum
above $\sim 100$~GeV in the current data still leaves some room for TeV scale
DM particles. More antiproton data at high kinetic energies are needed to
constrain the properties of the DM particles.
