Lewis Hamilton has moved to clarify comments he made about Formula One's push to race in countries with a limited wealth and racing heritage.
Hamilton, who last month secured his fifth world championship, has spoken out against certain aspects of F1's push to add races to the calendar, questioning recently whether the sport needed to add a Vietnam Grand Prix -- now confirmed for 2020 -- when there's already 21 races a year. This week he elaborated on his view in an interview with BBC Sport.
"On the racing side, I don't know how important it is to go to new countries as such," he said.
