Eight Chinese nationals were on board the crashed Ethiopian Airlines flight, Chinese state media report.
Earlier, the airline said all the 149 passengers and eight crew believed to be on the flight, from 33 nationalities, died in the Sunday morning crash.
Boeing, the company that built the crashed aeroplane, noted in a tweet that it was “closely monitoring the situation”.
Its 737 Max-8 aircraft is relatively new to the skies, having been launched in 2016. It was added to the Ethiopian Airlines fleet in July last year.
Another plane of the same model was involved in a crash five months ago, when a Lion Air flight crashed into the sea near Indonesia with nearly 190 people on board.
