Narrative:
Departing hrg (vhhk) on the elato 1 alpha SID, we were climbing outbound on the 104 degree radial from ch VOR, passing approximately 27000 ft when we requested direct elato to avoid 2 cloud buildups located to our left. This was denied and we were assigned a heading of 095 degrees. This allowed us to clear the buildups to the right. Shortly after we requested a heading of 060 degrees to avoid another area of showers ahead. This was approved. When we were clear of the showers, a clear area appeared on what I took to be the route to elato, which we requested and had approved. However, as we turned direct to elato we entered the coulds adjacent to the showers. As we reached FL305 the TCASII announced 'traffic' and a yellow TA symbol appeared half hidden at the top of the vsi. In about 5 seconds, it turned red and began to move down the right side of the instrument towards us. The vsi commanded a 2000-2500 FPM descent. I disconnected the autoplt and autothrottles and pitched over to capture the rate of descent. The target passed above us and to the right, approximately 400 ft and 1/2 mi. We informed ATC of our descent and were told to turn to a heading of 360 degrees and level at FL290. We were then reclred back to elato.

Title: A WDB ACFT HAS A TCASII RA DURING CLBOUT FROM HONG KONG.
Narrative: DEPARTING HRG (VHHK) ON THE ELATO 1 ALPHA SID, WE WERE CLBING OUTBOUND ON THE 104 DEG RADIAL FROM CH VOR, PASSING APPROX 27000 FT WHEN WE REQUESTED DIRECT ELATO TO AVOID 2 CLOUD BUILDUPS LOCATED TO OUR L. THIS WAS DENIED AND WE WERE ASSIGNED A HDG OF 095 DEGS. THIS ALLOWED US TO CLR THE BUILDUPS TO THE R. SHORTLY AFTER WE REQUESTED A HDG OF 060 DEGS TO AVOID ANOTHER AREA OF SHOWERS AHEAD. THIS WAS APPROVED. WHEN WE WERE CLR OF THE SHOWERS, A CLR AREA APPEARED ON WHAT I TOOK TO BE THE RTE TO ELATO, WHICH WE REQUESTED AND HAD APPROVED. HOWEVER, AS WE TURNED DIRECT TO ELATO WE ENTERED THE COULDS ADJACENT TO THE SHOWERS. AS WE REACHED FL305 THE TCASII ANNOUNCED 'TFC' AND A YELLOW TA SYMBOL APPEARED HALF HIDDEN AT THE TOP OF THE VSI. IN ABOUT 5 SECONDS, IT TURNED RED AND BEGAN TO MOVE DOWN THE R SIDE OF THE INST TOWARDS US. THE VSI COMMANDED A 2000-2500 FPM DSCNT. I DISCONNECTED THE AUTOPLT AND AUTOTHROTTLES AND PITCHED OVER TO CAPTURE THE RATE OF DSCNT. THE TARGET PASSED ABOVE US AND TO THE R, APPROX 400 FT AND 1/2 MI. WE INFORMED ATC OF OUR DSCNT AND WERE TOLD TO TURN TO A HDG OF 360 DEGS AND LEVEL AT FL290. WE WERE THEN RECLRED BACK TO ELATO.
