Qatar Airways is considering taking a stake in Germany's Lufthansa, to seize business opportunities in Germany, its chief executive Akbar al-Baker was quoted as saying by German news agency dpa on Sunday.

"We did not have Lufthansa privatized in Germany to have it nationalized in Qatar," a Lufthansa spokesman said, when asked to comment on the report.

Lufthansa CEO Carsten Spohr has repeatedly criticized Gulf carriers such as Qatar Airways, Emirates and Etihad Airways of receiving what he describes as unfair state subsidies.
