Narrative:

We departed sti on the reksa 2 departure. Cleared to 11000 ft, by puerto plata control. When approaching sgo VOR, controller cleared us to FL240. At the same time another aircraft was at 12000 ft about 3 mi north of sgo, heading south. It was then cleared to 7000 ft. We saw him on TCASII. He started a descent and we were still climbing through about 10800 ft cleared to FL240. We then saw him visually and shallowed our climb as he shallowed his descent. We then got a monitor vertical speed RA and passed approximately 300 ft under him. It wasn't a real problem due to TCASII and visual conditions. We were also talking to each other (the 2 flts). I think the controller confused our position, due to this being a non-radar environment. The controller apologized and admitted that it was his fault.
