Ecclestone suggested Europe could see fewer races in future with other countries, such as Thailand and Mexico, seeking slots.
"The fact is that we are a world championship, not a European championship, so maybe we are going to lose a couple of European races because we are going to other parts of the world," he said.
"There are lots of countries knocking at our door and it is a case of finding the right places for Formula One."
Russia is due to make its debut next year with a race in Winter Olympics venue Sochi.
