Airport; Human Factors; Procedure
We requested push from [the gate] in ZZZ and were told we were cleared to push by Ramp [Control]; expect XXC. We completed the before start checklist 'below the line' and told the ground crew we were ready to push. We pushed back around XA59Z and a few minutes into the push the ground crew slammed on the brakes; stopped the push; and told us Aircraft Y had taxied behind us very closely. I do not know what instructions the Ramp Controller gave them.Either the Ramp Controller was not paying attention when issuing the clearance to either my aircraft or Aircraft Y taxi clearance or the pilot misunderstood their clearance to taxi from the hard stand to the gate.
CRJ-900 Captain reported a ground conflict with another aircraft on the ramp during pushback.
