I think it unfair to blame anyone from this video. But we should consider how the airport was laid out and whether or not the Turkish Airbus was inside or outside the stand markings (that normally should exist). It would also be interesting to hear what taxi clearances were issued to aircraft in this vicinity and whether or not the ground controller responsible for this part of the airfield knew that the Turkish Airbus was not yet parked. I'd also like to know what speed the Asiana was taxying. With this information I might then start to form some opinion.
