Narrative:

We received an RA to climb heading into ZZZ. As we were approaching ZZZ about to begin our final decent; we were told my approach that a C172 was 500 ft. Below us to our 1-2 o'clock. We saw the traffic on TCAS but could not visibly see the traffic. We made ATC aware that we were looking for traffic. As the pilot flying; I realized that the aircraft was climbing and the nonflying pilot saw this as well. As this aircraft came to about 2-300 ft. Below us; we received the RA to climb which I did and let made ATC aware of this. After we were clear of conflict ATC told us the traffic should no longer be a factor. I'd suggest with VFR traffic that close it should have been given a lower altitude or maybe a heading to turn to; to avoid situations like this from happening in the future.
