Narrative:
Captain and relief first officer were changing seats when first officer noticed aircraft at same altitude (1-2 O'clock bearing 10-20 mi away). Aircraft was on constant bearing and closing. First officer recognized aircraft at same altitude and elected to leave FL350 climbing to FL370 -- to avoid collision with air carrier -- an airbus. TCASII advisory alerted crew with resolution. ATC cleared aircraft to FL370. Controller error was definitely a contributing factor. Controller never once announced traffic and seemed oblivious of a near miss.

Title: WDB AT CRUISE IN FOREIGN AIRSPACE HAS CLOSE PROX WITH ANOTHER ACR AT SAME ALT.
Narrative: CAPT AND RELIEF FO WERE CHANGING SEATS WHEN FO NOTICED ACFT AT SAME ALT (1-2 O'CLOCK BEARING 10-20 MI AWAY). ACFT WAS ON CONSTANT BEARING AND CLOSING. FO RECOGNIZED ACFT AT SAME ALT AND ELECTED TO LEAVE FL350 CLBING TO FL370 -- TO AVOID COLLISION WITH ACR -- AN AIRBUS. TCASII ADVISORY ALERTED CREW WITH RESOLUTION. ATC CLRED ACFT TO FL370. CTLR ERROR WAS DEFINITELY A CONTRIBUTING FACTOR. CTLR NEVER ONCE ANNOUNCED TFC AND SEEMED OBLIVIOUS OF A NEAR MISS.
