Sepang was Hermann Tilke’s first full creation. It made its grand prix debut in 1999.
But Razlan Razali, the Kuala Lumpur circuit’s chief executive, said on Wednesday that he is unable to say if there will be an F1 race there in 2016.
“We can recommend all we want, but as (the) prime minister announced last year, the decision will be made by the cabinet,” he told the New Straits Times.
Sepang commissioned consultants PricewaterhouseCoopers (PWC) last year to study the economic impact of the Malaysian Grand Prix.
“PWC advised us to have another study on this year’s event,” revealed Razali.
He also pointed some criticism at the lack of enthusiasm from some parts of the government, particularly when it comes to promoting the annual race.
“Not all ministries seem interested,” Razlan admitted.
