We revisit the host galaxy of GRB031203 using a set of spectra obtained with VLT. Assuming a Galactic color excess E(B-V)=0.72 (mag)in the direction of the burst,we derive an internal extinction of about 0.4 (mag). After correcting for reddening, we find an electronic density of 156 cm^{-3} and a temperature of 12443(K). With an ISM dominated by photo-ionization, we estimate a metallicity of 12+Log[O/H]=8.12 and a star formation rate of 12.3 (M_{o}yr^{-1}). This galaxy does not host a clearly detectable population of WR stars.
