A near threshold enhancement in the pp invariant mass spectrum has been reported by the BELLE, BES, and BABAR collaborations for several B and J/{psi} decays. This enhancement has been interpreted as a narrow baryonium state X(1835). We investigate its nature using a pp interaction derived from a constituent quark model. This interaction does not show any pp bound state but a {sup 3}P{sub 0} resonance. We show that pp final state interaction can reproduce the mass dependence of the pp mass spectrum close to the threshold observed in different B and J/{psi} decays.
