Egypt's Suez Canal Authority on the 30th announced the results of the investigation into the grounding accident of the cargo ship "Changzhi" in March this year, confirming that the captain of the cargo ship was responsible for the grounding accident. Suez Canal Authority held a press conference at its headquarters in the northeastern Egyptian city of Ismail on the same day. Said Shu Aisha, head of the investigation team of the Canal Administration, said that by analyzing the navigation data of the cargo ship involved, the investigation team determined that the captain's erroneous instructions were the main reason for the cargo ship's stranding, and the navigator sent by the Canal Administration did not bear the responsibility, because the navigator's proposal was "not mandatory."
