ATHENS--Greece's largest lender, the National Bank of Greece SA (NBG), said Monday that it had held talks with France's Credit Agricole SA (ACA.FR) over possible cooperation.

The statement, made to the Athens Stock Exchange, gave no details but comes following recent media reports suggesting that NBG could be a potential buyer of the French bank's Athens-based Emporiki Bank (TEMP.AT) subsidiary, which Credit Agricole is trying to sell in an effort to exit the Greek market.

"National Bank informs the investment community that there have been discussions between the management of National Bank and Credit Agricole about the possibilities of future strategic alliances, which as of today are at a preliminary stage," NBG said.

At the weekend, the Financial Times reported that NBG and rival Greek lenders Alpha Bank AE (ALPHA.AT) and EFG Eurobank Ergasias SA (EUROB.AT) have all expressed interest in taking over Emporiki, acquired by Credit Agricole from the Greek state in 2006.

The planned sale of Emporiki, first disclosed by The Wall Street Journal last month, comes as its French parent tries to cut its exposure to Greece after chalking up more than a billion euros worth of accumulated losses in the six years since it bought the Greek bank and following Greece's debt restructuring this year.

In May, Credit Agricole, one of the biggest banks in Europe by capitalization, reported a 75% drop in first-quarter net profit after it was hit by its exposure to the Greek debt crisis.

At the time, the company said total losses on Greece were 940 million euros ($1.2 billion) including costs linked to the Greek sovereign debt swap agreed in March and provisions related to its majority stake in Emporiki.
