We present a 30 ks XMM-Newton observation of the z = 2.35 Type II radio quiet quasar RXJ1343.4+0001. These data provide the first good quality X--ray spectrum for this object. We measured a continuum slope Gamma = 1.85+/-0.10 with only an upper limit on the column density of the absorbing material of Nh <~ 10e22 cm-2 as well as a Fe K_alpha emission line at the 3sigma confidence level. We do not find therefore a highly absorbed object neither a truly flat spectrum as suggested on the basis of previous less sensitive ROSAT and ASCA measurements.
