Narrative:

We were cleared direct to cesba; cross it at 9000 ft MSL; and cleared for the RNAV runway 29 approach into gjt. We crossed cesba at 9000 ft MSL and descended to 8500 ft MSL as per the charted approach procedures. At the next fix on the approach; hansu; there is a 90-degree turn to the final approach course. Prior to reaching hansu but level at 8500 ft MSL; ATC gave us an altitude alert for the nearby terrain. We were complying with the charted altitudes and courses for the approach. We told ATC that we were complying with the charted approach procedures; we turned 90 degrees and intercepted the final approach course inbound. We descended below the clouds; saw the runway and were cleared to land. Our GPWS equipment never alerted us to the terrain.
