The crew of flight 523 found a traffic 20 miles at FL 294 right ahead of the airplane on TCAS at FL 290 near LAMEN. The captain reported to Shanghai Control immediately, but the controller responded that there was no indication on his radar screen and there had not been any flight advisory. The captain then instructed the crew to turn left and found the conflicting traffic closing to the flight path and a TCAS warning was initiated. The crew then immediately turns right for avoidance, disengage the autopilot and descended to a lower altitude. The crew reported to the controller about the conflict after the conflict had been cleared.
