We were assigned Spot by ramp control. Upon contact with LAS ground control; the clearance was; (paraphrased); 'Taxi to Runway 25R; via [A#]; via B; hold short of A2.'We taxied single-engine and as we approached taxiway [A#]; the First Officer stated; 'STOP!' We held short of taxiway C while Aircraft Y went by at a high rate of speed. The distance between their winglet and our nose was probably 5 to 7 feet! Taxi speed for Aircraft Y was over 25 knots and possibly 30 knots.I have over 30;000 flight hours and this is the closest I have ever been to another aircraft where a potential for a collision during taxiing was evident.LAS Ground twice apologized for the event to us directly.Ground control did not issue instructions to [either Aircraft X or Y] on the potential for conflict; although we had converging clearances. We had the right of way from a priority perspective of relative distance; but the other aircraft was traveling at a faster taxi speed. Interestingly; there was a line up at the approach end for departure.Aircraft Y was approximately number four in the queue.Ground did not issue instructions that would have provided concise directions to either air carrier. Aircraft Y was taxiing at an apparent high rate of speed and was determined to get in the queue; then wait. We were lucky that the First Officer was studiously watching the other plane; and issued a forceful callout.I truly believe if Aircraft Y had to stop; it would have been abrupt.
Air carrier Captain reported near collision on ground due to Ground Control not providing correct instructions.
