BESIII has collected 2.9 of e+e- collision data sample at 3.773 GeV. We report recent measurements of strong phase differences in D0 and D0-bar decays of KSpi+pi-, KSK+K-, K-pi+pi+pi- and K-pi+pi0. The obtained parameters are important to reduce the systematic uncertainty in the gamma/phi_3 measurement at LHCb and Belle II.
