Narrative:

We departed zsss airport on runway 36 with clearance to maintain runway heading and 900 meters (2960 ft QFE). We were then cleared to turn left to heading 160 degrees and climb to 1200 meters (3940 ft QFE) followed by clearance to turn left direct to 'wb' beacon and climb to 1500 meters (2930 ft QFE). We were then instructed to turn right to heading 180 degrees. Shortly after turning to 180 degrees and level at 1500 meters, we received a TCASII TA and a visual display of traffic close in at about 8:30 - 9 O'clock position, 700 ft. The so and I acquired visual contact with a B757. The traffic appeared to be converging, slightly low, and turning to a collision course with us. We turned to a 195 degree heading and I told zsss departure control we turned to heading 195 degrees to avoid traffic. Control then told me to maintain heading 195 degrees and 1500 meters. I watched as the B757 passed close behind (within 1/4 mi) and slightly below. Close enough in my mind to be a near miss. Almost immediately thereafter, a second large aircraft, an airbus (?) passed directly through our altitude in a steep dive and high speed. The airbus appeared only momentarily on TCASII at +1100 ft and we didn't receive an aural warning. We estimate that was in a 20 degree nose down attitude and passed within 1/2 mi. We were then given clearance to turn left direct to nhw VOR and the rest of the flight was uneventful. Contributing factors in this chaotic situation were certainly reduced visibility (IMC -- 1 mi or less) and poor communications. All communications with the other aircraft were in chinese and therefore meaningless to us. The frequency was very congested, however, what little english was spoken was easily understood and the radio transmission quality was acceptable.

Title: B747 REQUIRED TO TAKE EVASIVE ACTION TO AVOID 2 FOREIGN CARRIERS WHILE DEPARTING IN ZSSS CTL.

Narrative: WE DEPARTED ZSSS ARPT ON RWY 36 WITH CLRNC TO MAINTAIN RWY HDG AND 900 METERS (2960 FT QFE). WE WERE THEN CLRED TO TURN L TO HDG 160 DEGS AND CLB TO 1200 METERS (3940 FT QFE) FOLLOWED BY CLRNC TO TURN L DIRECT TO 'WB' BEACON AND CLB TO 1500 METERS (2930 FT QFE). WE WERE THEN INSTRUCTED TO TURN R TO HDG 180 DEGS. SHORTLY AFTER TURNING TO 180 DEGS AND LEVEL AT 1500 METERS, WE RECEIVED A TCASII TA AND A VISUAL DISPLAY OF TFC CLOSE IN AT ABOUT 8:30 - 9 O'CLOCK POS, 700 FT. THE SO AND I ACQUIRED VISUAL CONTACT WITH A B757. THE TFC APPEARED TO BE CONVERGING, SLIGHTLY LOW, AND TURNING TO A COLLISION COURSE WITH US. WE TURNED TO A 195 DEG HDG AND I TOLD ZSSS DEP CTL WE TURNED TO HDG 195 DEGS TO AVOID TFC. CTL THEN TOLD ME TO MAINTAIN HDG 195 DEGS AND 1500 METERS. I WATCHED AS THE B757 PASSED CLOSE BEHIND (WITHIN 1/4 MI) AND SLIGHTLY BELOW. CLOSE ENOUGH IN MY MIND TO BE A NEAR MISS. ALMOST IMMEDIATELY THEREAFTER, A SECOND LARGE ACFT, AN AIRBUS (?) PASSED DIRECTLY THROUGH OUR ALT IN A STEEP DIVE AND HIGH SPD. THE AIRBUS APPEARED ONLY MOMENTARILY ON TCASII AT +1100 FT AND WE DIDN'T RECEIVE AN AURAL WARNING. WE ESTIMATE THAT WAS IN A 20 DEG NOSE DOWN ATTITUDE AND PASSED WITHIN 1/2 MI. WE WERE THEN GIVEN CLRNC TO TURN L DIRECT TO NHW VOR AND THE REST OF THE FLT WAS UNEVENTFUL. CONTRIBUTING FACTORS IN THIS CHAOTIC SIT WERE CERTAINLY REDUCED VISIBILITY (IMC -- 1 MI OR LESS) AND POOR COMS. ALL COMS WITH THE OTHER ACFT WERE IN CHINESE AND THEREFORE MEANINGLESS TO US. THE FREQ WAS VERY CONGESTED, HOWEVER, WHAT LITTLE ENGLISH WAS SPOKEN WAS EASILY UNDERSTOOD AND THE RADIO XMISSION QUALITY WAS ACCEPTABLE.
