Who won the Chinese grand prix in 2002?
There was no Chinese Grand Prix until 2004. If you meant the 2002 Japanese Grand Prix, that was won by Michael Schumacher (with Barrichello and Räikkönen finishing second and third). If you meant the 2004 Chinese Grand Prix, that was also won by Michael Schumacher (with Ralf Schumacher second and Jenson Button third). I hope that helps.
