IAAF president Sebastian Coe has accused Nestle of hypocrisy following its decision to bring a premature end to its association with athletics' governing body.
On Wednesday, the Swiss-based food and beverage company announced it was to terminate its sponsorship of the IAAF's Kids Athletics programme, which it had helped fund since 2012.
Nestle stated that fears over its reputation due to the corruption and doping scandal embroiling the IAAF was the reason for its decision.
However, Coe says Nestle's sponsorship of the Tour de France during a period of considerable turmoil for cycling renders that point void.
"We were left confused and angry. I didn't understand the rationale behind it," Coe told BBC Sport.
"Clearly it wasn't a decision made about reputation because, since 2001, they've been the global partner to the Tour de France, and renewed at a moment when cycling was in its worst position around doping.
"We felt this was hypocritical."
Last month, sportswear giant Adidas said it remained in "close contact" with the IAAF amid reports it has ended its partnership with the body.
