Leading French firm Gide Loyrette Nouel has re-established a presence in the Middle East, becoming the second Big Law firm to open an office in Iran.

The firm’s new Tehran office will be headed by international trade and regulatory partner Mehrnoosh Aryanpour, who joined 600-lawyer Gide earlier this year from Gibson, Dunn & Crutcher, where she was of counsel. The practice will also be overseen by Paris-based corporate partner Christophe Eck, who served as the firm’s global managing partner between 2010 and 2011.
