Narrative:

Cruising FL330 abeam and (taipei control) received TCASII (TA) which turned to (RA) to descend 2200 FPM to avoid air carrier Y A300? Autoplt was disconnected and RA was followed to descend 2500 FPM. A visual contact was established with Y also at about 5-6 mi. I was flying the RA plus visual in an effort to avoid. Passed about 1/2 mi abeam Y about 300 ft lower than him. I believe at this time he was attempting to return to his assigned altitude of 310. I descended to about 32100 ft when we passed each other.
