Narrative:

We were airborne from mmgl runway 28. Tower switched us to approach control and started speaking spanish to a domestic mexican aircraft. With the spanish; we had no idea where the aircraft was. As we climbed through 7;000 feet MSL we got a TCAS advisory which then turned into a TCAS RA with a 'descend; descend' command. We followed TCAS RA procedures and as I tried to visually acquire what I thought would be a GA airplane; [an airline aircraft] flushed out at our 5' clock position approximately 100 feet above and 300 feet laterally. Guadalajara departure said nothing to us neither did tower. The other aircraft had executed a go around and was over taking us and being above us the whole way probably did not have us in sight.
