Mad men, bad men: how three GroupM China bosses pocketed $176m in ad-rebate kickbacks

CHINA: Advertising is meant to sell dreams. In Shanghai, it sold something rather more lucrative: a 1.2 billion yuan ($176 million) kickback racket that has just landed a media baron a life sentence. In March 2026, a Shanghai court quietly convicted three former GroupM China executives of commercial bribery, in what ranks among the largest private-sector corruption prosecutions in the country’s advertising history. Di Fei, the unit’s former chief investment officer, got life. Yao Lan got 14.5 years. Hong Xin got four. The verdicts, kept under wraps per China’s opaque rules on private bribery rulings, only surfaced via Bloomberg reporting.

The scheme was as simple as it was shameless. Between 2019 and 2023, GroupM, WPP’s media-buying behemoth, outsourced chunks of its clients’ ad-spending to external broker firms. These brokers pooled enormous budgets from global brands to squeeze fat volume discounts and rebates out of media platforms, sometimes as much as 20 per cent of a client’s entire budget. Standard practice says those rebates flow back to the client. Instead, the brokers pocketed them as their own income.

To keep their grip on WPP’s fat pipeline of business, the brokers then funnelled a slice of those withheld rebates straight into bank accounts belonging to Di, Yao, and Hong. Over the years, that “slice” snowballed into a staggering $176 million. And WPP itself wasn’t merely an innocent bystander watching the cash fly past: the court heard the firm leaned on these same subcontractors to buy WPP products, hand over steep discounts, or render free services, demands the brokers met, fearful of losing the agency’s lucrative business altogether.

The scandal first burst into daylight in October 2023, when China’s economic crime investigators raided GroupM’s Shanghai office and detained senior executives. Patrick Xu, then GroupM China’s chief executive and WPP China’s country managing director, was questioned but never detained. WPP moved fast: it fired the detained staff, froze trading with the broker agencies under the scanner, and parachuted in a fresh leadership team. It took until June 2026 for WPP to formally acknowledge the sentences, insisting it was “not a direct party” to proceedings but had “cooperated fully” with Chinese authorities and respected the court’s call.

Di Fei, unsurprisingly, isn’t taking life imprisonment lying down. His appeal hinges on two punchy arguments. First, that because WPP exercised de facto control over the brokers’ businesses, the money should be reclassified as garden-variety “misappropriation of corporate funds” rather than criminal bribery, a neat bit of legal jiu-jitsu that could slash his sentence dramatically. Second, his lawyers are contesting the prosecution’s eye-watering $176 million figure outright, hoping to chip away at the scale of the case itself.

China’s courts are expected to rule on that appeal sometime between late 2026 and early 2027. Until then, Di sits in limbo, the brokers count the cost of their compliance, and WPP’s once-untouchable China operation nurses a reputational bruise that no amount of ad spend can buy back.
