During Pushback in LAS the Ramp controller gave Aircraft Y clearance to enter the ramp area on the green line; taxi around the Aircraft pushing off (us) on the yellow line; and then to resume the green line to their gate. I advised our ground crew to watch out for Aircraft Y taxiing inbound based upon prior experience and the confusion in read back by the Aircraft Y crew. As I did so; over my left shoulder I noticed Aircraft Y taxiing at a high rate of speed; not appearing to slow or change to the yellow line to avoid a collision with our aircraft. I advised the ground crew to stop pushback of our aircraft as quickly as possible. I keyed the mic on ramp frequency stating that 'We are stopping the push as it appears Aircraft Y was not going to give way.' The ramp controller stated that Aircraft Y needed to stop at their current position. Aircraft Y failed to follow her additional instructions to enter the hold pad. We completed our push; started our engines and were cleared to taxi to spot around Aircraft Y. It is my opinion that if I had not acted by stopping our push; and keyed the mic and broadcast that we were stopping our push; Aircraft Y would have taxied into our aircraft at speed causing major damage to both aircraft. Aircraft Y's speed took them to within 80-100 feet of our aircraft during their rapid stop. The pushback crew needs to be commended for a job well done; as they were already acting to stop the aircraft as I stated to stop the pushback. The ramp area is a congested area of the airport and when dealing with international carriers; complicated taxi procedures on the ramp may need to be avoided to keep down any confusion by international carrier crews.
Air Carrier Captain reported a potential collision during pushback with traffic that failed to give way.
