Narrative:
During initial climb to 9;000 departing runway 21 we received a traffic alert as there was an airliner approaching from the west; I believe the aircraft was at 10;000 ft. Pilot flying slowed the rate of climb; am not sure of the sequence; however ATC cleared us to I believe FL200 as we were making the turn northwest bound and in that sequence; turning northwest; we heard the aircraft that was approaching from the west tell ATC they received an RA and we did as well that stated 'monitor vertical speed' however it lasted for less than 2 seconds. We did see the aircraft to our left and appeared roughly a mile away. I believe the major factors are the proximity of the astah intersection on the SID and possibly the fix that the other aircraft was going to; I can only assume that the other aircraft was flying the KRKEE1 RNAV arrival and was in the proximity of stiki. In my opinion this will occur again due to the proximity of these 2 intersections and the climb capabilities of many aircraft; this clearly was a forecasting event which both TCAS predicted. I am not sure if there is a clear solution other than to move those two intersections or redesign the 2 procedures.

Title: Corporate aircraft departing ABQ experienced a TCAS RA with an arrival aircraft; the reporter suggesting the close proximity of arrival and departure navigational fixes could be one causal factor.
