Petrobras on Wednesday agreed to settle a class action lawsuit in the United States that claimed damages for the oil company's role in a bribery scheme involving company executives and government officials. Petrobras said the settlement was not an admission of guilt and denied any wrongdoing.

"The voluntary act of Petrobras paying $3 billion to foreign shareholders indicates it should pay proportional values to Brazilian shareholders," Andre de Almeida, a lawyer leading the shareholder lawsuit in Brazil, told Reuters.

"After all, the same facts, the same defendants, should have the same consequence, independent of the jurisdiction of the investment."

Petrobras declined to comment.

Wednesday's settlement agreement, which must still be approved by a U.S. court, was one of the largest ever class action settlements in the United States.

For the last four years Brazil has been rocked by the so-called Car Wash investigation into kickbacks from contractors to executives of state-run companies and politicians in return for public projects.
