B777 FLC HAS POSSIBLE RWY INCURSION AFTER MISTAKING CLRNC ISSUED BY ZBAA TWR.

Narrative

HOLDING SHORT OF RWY 36R FOR TKOF. ACFT ON RWY STARTING TKOF ROLL. TWR CALLS 'ACR X; CLRED RWY 36R POS AND HOLD.' BECAUSE I KNOW THEY USUALLY SAY 'LINE UP AND WAIT' I SLOWLY REPLY CLRNC AND TWR SAYS NOTHING. TWR HAS CLR VIEW OF ARPT AND VISIBILITY WAS 9999; SO WE TAXIED INTO POS. SAT FOR ALMOST 2 MINS WHEN WE SEE AN ACFT GOING AROUND. TWR ASKS US TO TAXI OFF RWY. WE ASK IF WE MISUNDERSTOOD CLRNC. NO ANSWER. THEY HAD US TAXI AROUND TO HOLD SHORT POINT AGAIN; AND THEN CLRED US TO TAKE OFF ASKING IF WE WOULD ACCEPT IMMEDIATE TKOF. IT WAS ODD THAT THEY DID NOT EXPLAIN ANYTHING. I FEEL THAT THE PRESSURE OF NOT ADMITTING A POSSIBLE MISTAKE WEIGHS HVY ON A CTLR FROM A COUNTRY LIKE CHINA. HE MAY LOSE HIS JOB. HE MAY HAVE INTENDED THE FIRST TIME TO GIVE US AN IMMEDIATE TKOF AND FORGOT ABOUT US; OR WE MAY HAVE MISINTERPRETED HIS CALL. EITHER WAY; THE LANGUAGE BARRIER IS POTENTIAL FOR A SERIOUS PROB; IF WX WERE A FACTOR. CHINA ALSO HAS A HABIT OF ASKING QUESTIONS AS YOU ARE BRINGING UP THE GEAR LIKE; 'CAN YOU ACCEPT 11400 METERS' WHILE GIVING YOU OTHER INSTRUCTIONS. OUR CLRNC IS FOR 10200 METERS AND THEY COULD ASK THIS QUESTION MUCH LATER. IN CLOSING; COMS IN THE PACIFIC SHOULD BE ADDRESSED.
