Qatar Investment Authority, the country's sovereign wealth fund, is keen to buy part of the U.S. Treasury's stake in Citigroup Inc , the Financial Times reported in its Wednesday edition.

Citing people familiar with the matter the paper said QIA was considering purchasing some of the U.S. Treasury's 27 percent stake in Citigroup, but warned any deal would be dependent on price and market conditions.

The U.S. treasury said in April it was launching its plan to sell of its 7.7 billion share stake in Citigroup. Morgan Stanley is advising the U.S. government on the sale of up to 1.5 billion common shares.
