After we received taxi Inst from ZZZZ ground to taxi X to Y to XXL hold point we proceeded as instructed. We stopped at the intersection of X and Y because a Aircraft Y was holding on Y. I stopped shorter than I normally do because I didn't want to be sitting in his Number 1 engine wake while sitting still. We had brakes parked. My First Officer looked to his right and commented that an aircraft was approaching from the right on Taxiway Y. After a few seconds he said he's coming fairly fast and it didn't look as if he was slowing. We both realized at the same time he was going to continue and not stop. I flashed my R turnoff lights then my taxi lights to alert him of our close relationship. He never slowed. My First Officer made two 'aircraft stop' transmissions with no reaction. Looking at his wingtip approaching our cockpit I made the comment 'hang on guys' and his wingtip passed within 10 feet. of our windscreen. We told ATC of what happened. She came back and said; 'sorry for [the] inconvenience.' I have never been so mad and scared in my over 30 years here at [Company]. There are no holding lines or holding instructions given to us. We were cleared to the runway. Either Ground Control or Aircraft Y made a horrible mistake; potentially ending our lives by driving their wingtip through our cockpit.I think either ATC gave two clearances to both of us Aircraft X and Aircraft Y; or Aircraft Y had an ATC taxi violation. Regardless Aircraft Y either ignored our lights flashing and radio calls or was not looking outside past the center line of the taxiway. I have no clue to his thought process.If a Tower Frequency change was given to Aircraft Y prior to our intersection; that policy MUST stop. If he could have heard us tell him to stop it would have prevented a possible collision. If he heard us and ignored us; God help us all.
B777 flight crew reported ATC instructions caused a critical ground conflict with another aircraft.
