Aerospace giant Bombardier, which employs around 4,000 people in Belfast, has secured a $106m (£81m) deal to sell three Q400 aircraft to a Bangladeshi airline.
Biman Bangladesh Airlines has ordered the new Q400 turboprops, which contain components made in Belfast. It already flies two of the aircraft.
Francois Cognad, vice-president of Asia Pacific sales for Bombardier, said: "We are very pleased that Biman is expanding its Q400 fleet with this order for three new aircraft.
"The Q400's greater seating and cargo capacity really set it apart from the competition.
"Furthermore, the Q400's mix of turboprop economics and jet-like performance were the best match for Biman's mix of short and long-range routes.
"Operators coming back for more Q400 aircraft really validates the benefits of the aircraft's unique characteristics."
AM Mosaddique Ahmed, managing director of Biman Bangladesh Airlines, said it was "very excited" about the deal.
"With its outstanding economics, comfort and operational flexibility, the Q400 will allow us to offer high frequency services within Bangladesh and neighbouring countries," he said.
The deal was supported by trade organisation Canadian Commercial Corporation (CCC).
Ian McLeod of CCC said: "Canada and Bangladesh enjoy strong bilateral ties through trade and investment development co-operation. Increasing the capacity of the national carrier supports these efforts and the economic growth of the country."
