Qatar Airways on Thursday said that it had acquired 10-per cent stake in Chile's LATAM Airlines Group for USD 608 million.
The Doha-based state airline announced the stock purchase late on Thursday.
LATAM was created when Chile's LAN took over Brazil's TAM in 2012. The airline flies to some 140 destinations in 25 countries. LATAM stock closed at USD 8.42 a share yesterday, up 1.6 per cent.
Qatar Airways operates a fleet of 192 aircraft out of its hub in the vast new Hamad International Airport in Doha, which is preparing to host soccer's World Cup in 2022.
It is one of the Middle East's biggest carriers, along with Dubai-based Emirates Airline and the Abu-Dhabi based Etihad Airways. The three airlines increasingly have challenged Western airlines in long-haul flights.
