Narrative:

On the cheonja arrival from nrt into seoul we were given a vector of 270 degrees and maintain 8000 ft prior to the anyang (sel) VOR. We read back the clearance. Out of approximately 9000 ft TCASII gave us a TA, soon followed by an RA to 'monitor vertical speed.' we were IMC and the traffic (which is usually stopped at 7000 ft over sel) was climbing right to left. TCASII called for 2500 ft descent which the captain did. (But it was hard to follow as it had us descending into traffic which now seemed to be leveling off at 8000 ft.) at the same time we initiated a turn to the right and the descent command reduced. Moments later ATC calls and rapidly told us to stop descent and turn right to 320 degrees. We had already done that! Had it not been for TCASII we would have looked at each other and said 'what did he say?' and gone 'splat' over the countryside! On the ground ATC called and asked if we wanted to file a police report. We went to the tower to let them see the lives behind the blips and verify lessons had been learned. Captain is retiring in a few months and so is retired, so this will be the only report on this incident.

Title: CONFLICT AIRBORNE LESS SEVERE.

Narrative: ON THE CHEONJA ARR FROM NRT INTO SEOUL WE WERE GIVEN A VECTOR OF 270 DEGS AND MAINTAIN 8000 FT PRIOR TO THE ANYANG (SEL) VOR. WE READ BACK THE CLRNC. OUT OF APPROX 9000 FT TCASII GAVE US A TA, SOON FOLLOWED BY AN RA TO 'MONITOR VERT SPD.' WE WERE IMC AND THE TFC (WHICH IS USUALLY STOPPED AT 7000 FT OVER SEL) WAS CLBING R TO L. TCASII CALLED FOR 2500 FT DSCNT WHICH THE CAPT DID. (BUT IT WAS HARD TO FOLLOW AS IT HAD US DSNDING INTO TFC WHICH NOW SEEMED TO BE LEVELING OFF AT 8000 FT.) AT THE SAME TIME WE INITIATED A TURN TO THE R AND THE DSCNT COMMAND REDUCED. MOMENTS LATER ATC CALLS AND RAPIDLY TOLD US TO STOP DSCNT AND TURN R TO 320 DEGS. WE HAD ALREADY DONE THAT! HAD IT NOT BEEN FOR TCASII WE WOULD HAVE LOOKED AT EACH OTHER AND SAID 'WHAT DID HE SAY?' AND GONE 'SPLAT' OVER THE COUNTRYSIDE! ON THE GND ATC CALLED AND ASKED IF WE WANTED TO FILE A POLICE RPT. WE WENT TO THE TWR TO LET THEM SEE THE LIVES BEHIND THE BLIPS AND VERIFY LESSONS HAD BEEN LEARNED. CAPT IS RETIRING IN A FEW MONTHS AND SO IS RETIRED, SO THIS WILL BE THE ONLY RPT ON THIS INCIDENT.
