We have obtained a high spatial resolution X-ray image of the nucleus of NGC1068 using the High Resolution Camera (HRC-I) on board the Chandra X-rayObservatory, which provides an unprecedented view of the innermost 1 arcsecondradius region of this galaxy. The HRC image resolves the narrow line regioninto X-ray emission clumps matching bright emission-line clouds in the HST[OIII]5007 images and allows comparison with sub-arcsecond scale radio jet forthe first time. Two distinct X-ray knots are revealed at 1.3-1.4 arcsecondnortheast and southwest of the nucleus. Based on the combined X-ray, [OIII],and radio continuum morphology, we identify the locations of intense radiojet-cloud interaction. The [OIII] to soft X-ray ratios show that some of theseclouds are strongly affected by shock heating, whereas in other locations thejet simply thrusts through with no signs of strong interaction. This is furtherstrengthened by the presence of a kT~1 keV collisionally ionized component inthe ACIS spectrum of a shock heated cloud (HST-G). We estimate that thekinematic luminosity of the jet-driven shocks is 6x10^{38} erg/s, a negligiblefraction (10^{-4}) of the estimated total jet power.
