Talks to renew Malaysia's F1 contract are still ongoing.
Last month, Sepang circuit boss Razlan Razali travelled to London to discuss the expiring deal with F1 supremo Bernie Ecclestone.
"I am very confident this year's F1 (race) won't be the last," he said.
Three weeks on, a deal for 2016 and beyond still has not been struck.
Sepang chairman Mokhzani Mahathir told local media on Wednesday that the talks with Ecclestone are still taking place.
"The talks are centred on an agreeable price for organising the prestigious race for the next three years," he told the Bernama news agency.
"We also have to take into consideration the current economic volatility. For now we have not made any decision yet."
The report said the outcome of the talks will be known by March 29, when Sepang hosts the second round of the 2015 world championship.
