On YV8c departure from PEK; we experienced an apparent GPS jamming event. Similar to what occurs going into TLV except in a much more critical flight phase. At approximately 3;000 ft.; we got an ADS R out msg.  As we were familiar with the TLV events we immediately noticed the GPS was inoperative and we were in inertial navigation.  This lasted till about 12;000 feet and totaled 6 to 8 minutes.  What makes this different is that eventually our ANP exceeded our RNP for about 15 seconds.  As this was in the departure phase the RNP was 1.0 and our ANP got to 1.16.  Since we routinely do RNAV departures from PEK this could be a serious issue if it continues.
First Officer reported experiencing GPS jamming during departure from Beijing Capital Airport.
