A partial wave analysis of {chi}{sub c0}{yields}{pi}{sup +}{pi}{sup -}K{sup +}K{sup -} in {psi}(2S){yields}{gamma}{chi}{sub c0} decay is presented using a sample of 14x10{sup 6} {psi}(2S) events accumulated by the BES II detector. The data are fitted to the sum of relativistic covariant tensor amplitudes for intermediate resonant decay modes. From the fit, significant contributions to {chi}{sub c0} decays from the channels f{sub 0}(980)f{sub 0}(980), f{sub 0}(980)f{sub 0}(2200), f{sub 0}(1370)f{sub 0}(1710), K*(892){sup 0}K*(892){sup 0}, K{sub 0}*(1430)K{sub 0}*(1430), K{sub 0}*(1430)K{sub 2}*(1430)+c.c., and K{sub 1}(1270)K are found. Flavor-SU(3)-violating K{sub 1}(1270)-K{sub 1}(1400) asymmetry is observed. Values obtained for the masses and widths of the resonances f{sub 0}(1710), f{sub 0}(2200), f{sub 0}(1370), and K{sub 0}*(1430) are presented.
