We present improved measurements of the branching fractions of the color-suppressed decays B{sup 0}{yields}D{sup (*)0}h{sup 0}, where h{sup 0} represents a light neutral meson {pi}{sup 0}, {eta} or {omega}. The measurements are based on a data sample of 140 fb{sup -1} collected at the {upsilon}(4S) resonance with the Belle detector at the KEKB energy-asymmetric e{sup +}e{sup -} collider, corresponding to 7 times the luminosity of the previous Belle measurements. All the measured branching fractions fall in the range 1.4-2.4x10{sup -4}, which is significantly higher than theoretical predictions based on naive factorization.
