Kuala Lumpur was touted as one of the host cities for the Formula One World Championship from 1999 to 2017. The open-wheel auto racing A1 Grand Prix was held until the series folded in 2009. The Motorcycle Grand Prix races are held at the Sepang International Circuit in Sepang in the neighbouring state of Selangor. The Formula One event contributed significantly to tourist arrivals and tourism income to Kuala Lumpur. This was evident during the Asian financial crisis in 1998. Despite cities around Asia suffering declining tourist arrivals, Kuala Lumpur tourist arrivals increased from 6,210,900 in 1997 to 10,221,600 in 2000, or 64.6% increase in tourist arrivals. In 2015, the Kuala Lumpur Street Circuit was constructed to host the Kuala Lumpur City Grand Prix motor racing event.
