KUALA LUMPUR, Malaysia (AP) -- Malaysia is yet to decide whether it wants to keep hosting the Formula One race when its contract expires in 2010, a spokesman for the Malaysian venue said Monday confirming a news report.

Sepang International Circuit chairman Mokhzani Mahathir was quoted by the New Straits Times as saying the government has received a new contract for a five-year extension until 2015 but that it is still weighing the viability of several new clauses attached to the contract.

"We have received the contract to host the World Championship until 2015 but we have not signed it yet," he said in the report. The report didn't reveal details of the new clauses.

In an e-mail to The Associated Press, Mokhzani only said he would issue a statement soon on the matter.

A spokesman for the Sepang International Circuit, Azhar Ghazali, confirmed the report but declined to give further details.

The newspaper said the situation has become complicated as neighboring Singapore is bidding to secure a slot on the F1 calendar as early as next year, with plans for night races on a city circuit.

Sports Minister Azalina Othman earlier this month said Malaysia, which has hosted the Grand Prix since 1999, wasn't worried about Singapore's F1 bid but stressed there should only be one race in the region.

The New Straits Times said Formula One boss Bernie Ecclestone, during the Sepang race earlier this month, gave a vote of confidence for Malaysia to continue to host the race but criticized the circuit for being dirty and "shabby."

"There is rubbish all over the place and it's not really a good sign for Malaysia. We're on worldwide television and it needs to look good, much like in the beginning," Ecclestone was quoted as saying during the Malaysian leg of the Grand Prix two weeks ago.

Mokhzani acknowledged that there were shortcomings in the circuit but told the newspaper that a major upgrade, including building an "automotive-related theme park," would begin if the deal for the race to continue was inked.
