The Malaysian government is yet to decide whether to keep hosting an annual formula one race at Sepang beyond 2015.
"We will see," said prime minister Datuk Seri Najib Tun Razak after Sunday's 2011 event outside Kuala Lumpur. "The cabinet will decide," he told reporters at the circuit.
The PM said he was happy with Sunday's bigger crowd than usual - more than 100,000 - and sounded optimistic about the future.
"I believe this championship can increase Malaysia's profile internationally," said Najib.
The first Malaysian grand prix at Sepang was held in 1999.
