In recent weeks…TBWA's Beijing office has been running a campaign focused on Chinese pride, showing Chinese athletes supported by throngs of fans. At the same time, the agency's Paris office was working on another ad campaign on behalf of Amnesty International that showed Chinese athletes being tortured by Chinese authorities… Chinese bloggers…are now calling for a boycott of all TBWA ads … Amnesty's London headquarters decided weeks ago to spike the ads… But Amnesty still allowed TBWA [part of Omnicom] to run the ads once so they could be entered into the Cannes competition… TBWA's headquarters in New York said it wasn't aware of the campaign. "Had TBWA management known about this ad, not only would the ad not have been entered into an award show, but it would not have been produced," said Tom Carroll, chief executive of TBWA Worldwide… TBWA has a policy in the U.S. that bars it from doing political ads… And while the relationship with Amnesty has been fruitful for the agency in terms of publicity and honors, that relationship is "now under discussion," according to a person familiar with the agency.
