Laurent Fabius foreign minister France said: "If there is a violation of a rule, it is normal to have a penalty, but the penalty must be proportional and reasonable."

"We are in talks with the US for a transatlantic partnership. This trade partnership can only be established on a basis of reciprocity.

In addition, French officials have raised issues that the case will increase legal uncertainties for companies trying to do business in the US.

French officials are concerned that a big fine and suspension of dollar trading would damage BNP’s capital base, limit its ability to lend to the French economy and lose it international customers.
