Narrative:

Sbound victor airway 301, 30 KM north baq at FL330. Had TA (TCASII). Within 3-5 seconds, got RA to climb! Began immediate climb. Within 5 seconds, got RA to descend now! Pushed over and rolled left. Saw aircraft dead ahead 1-2 mi. (At time received RA, TCASII showed an aircraft 200 ft below and climbing.) skec said they had an heavy transport which had climbed to FL350! The aircraft we avoided at FL330 was climbing. The aircraft passed to our right approximately 1000 ft and slightly above. When the aircraft went off our display, he was plus 900 ft at 10 mi behind us. No injuries. Possibly would not have occurred if skec and other aircraft had clrncs in english! Other aircraft may not have had TCASII, from conversation with skec when they asked for his altitude, etc. Callback conversation with reporter revealed the following: the reporting captain flies a widebody transport aircraft, 2-MAN cockpit with a relief first officer when required. There were 2 aircraft flying northbound, one at FL310 and the intruder reporting level at FL350. Actually, the intruder aircraft was still climbing, through FL330 for FL350 when this incident occurred. The reporter started to follow the 'climb' command, but then received a 'descend' command. The reporter banked left slightly, and the intruder passed. There was very little altitude or track deviation by the reporting aircraft. The reporter states that it is a common practice for the south american air carrier's to turn off their xponders while airborne, and there is a continuing language problem. The reporter is near retirement and is ready.
