Jenson Button says he would welcome a F1 race in Moscow but first it has be established whether the Sochi GP is successful.
Button took part in the annual Moscow City Racing demonstration and was impressed with the event which once again brought the topic of a Moscow F1 race to the forefront.
The city's government wants to build a track in the southern suburbs of Moscow, which, if it comes to fruition, could mean two races as the first Russian GP will be held next year in Sochi.
"I don't think there's any reason not to have two grands prix in one country," Button told R-Sport.
The Brit, though, did add that he thinks "first we should concentrate on what we can do with the Sochi track. Let's not get ahead of ourselves."
"This here, the Moscow City Racing, is perfect a year in advance of the grand prix. There are motorsport fans here, but I'm sure there are other people who have never watched Formula One on TV will be interested in the sport by seeing a Formula One car pass today.
"So this is fantastic promotion, if you like, for the grand prix next year in Sochi."
