We consider the critical dynamics of a system with an n -component nonconserved order parameter coupled to a conserved field with long-range diffusion. An exponent characterizes the long-range transport, being the known locally conserved case. With renormalization group calculations done up to one loop order, several regions are found with different values of the dynamic exponent z in the - n plane. For n<4 , there are three regimes, I: nonuniversal, dependent z , II: universal with z depending on n and III : conservation law irrelevant, z being equal to that in the nonconserved case. The known locally conserved case belongs to regions I and II.
