The Group of Eight leaders signed up for a string of aims including improved transparency about who owns shell companies and more information-sharing between tax authorities.
British Prime Minister David Cameron has sought to clamp down on secret flows of money, making it a centrepiece of his presidency of the G8 this year.
But the communiqué did not contain a firm pledge to create registers of the "beneficial" - or true - owners of companies that would be available to tax authorities and law enforcement.
Les pays membres du G8 ont déclaré qu’ils adopteraient une position plus ferme en matière de lutte contre le blanchiment d’argent et la fraude fiscale. Ils n’ont toutefois pas détaillé les mesures spécifiques à l’issue d’un sommet de deux jours hier (18 juin).
