Malaysia GP officials are yet to sign a five-year contract extension despite previous claims they had secured a deal.
Sepang circuit organisers apparently have a contract on the table from Formula One Management for the event to be staged through to 2015.
However, they have yet to put pen to paper as it is understood a number of clauses are currently being assessed.
Speaking to the New Straits Times, Sepang chairman Datuk Mokhzani Mahathir said: "Yes, we have received the contract to host the world championship until 2015, but we have not signed it yet."
