  In this talk we review the important role played by chiral SU(3) symmetry in
hadron physics. Exciting new results on the formation of baryon resonances as
implied by chiral coupled-channel dynamics are presented and discussed. The
results are the consequence of progress made in formulating a consistent
effective field theory for the meson-baryon scattering processes in the
resonance region. Strangeness channels are found to play a decisive role in the
formation of resonances. As a further application of chiral coupled-channel
dynamics the properties of antikaons and hyperon resonances in cold nuclear
matter are reviewed.
