Organisers of the European Grand Prix at Valencia have denied specifically asking to pay a lower race sanctioning fee.
"We are not aware of any ongoing negotiation," the regional economy minister is quoted by EFE news agency.
Minister Gerardo Camps also said he is aware of Valencia's "obligations", amid speculation the 2010 fee was not paid because the organisers are pushing for contract amendments.
"The government at this time has not proposed to change any of the obligations we have with the organisation of Formula One," he insisted.
Camps also said he is not aware if "other countries, circuits or organisations are entering into negotiations" to change the terms of their own F1 contracts.
