Narrative:

Sbound on A567 at 35000 ft over dusan intersection we were rapidly closing in on traffic at 35000 ft opposite direction. We started deviating west of course and then received a TCASII alert to climb. We climbed to 35700 ft as an A300 passed below us. We were talking with curacao control and had reported level at FL350 at berox intersection.
