For GRB 011211 XMM detected fading X-ray object with an average flux in 0.2-10 keV declining from 2.7$\\times10^{-13}$ erg cm$^{-2}$ s$^{-1}$ during the first 5 ks of 27-ks observation to 1.0$\\times10^{-13}$  erg cm$^{-2}$ s$^{-1}$ toward the end of the observation. The spectrum of the afterglow can be fit to a power law with alpha=2.16$\\pm$0.03 modified for the Galactic absorption. No significant evolution of spectral parameters has been detected during the observation.
