I know the importance of China's National Games, and it is not only for the athletes but for the whole population,

Security worked extremely well, the athletes are happy. They were definitely games that pleased the athletes. The competitions were at a very high level.

For the thousands of athletes who compete cleanly and fairly, we have a duty to put in place the strongest measures to trap the small minority who cheat.

I think the deterrent effect and the message has been sent since Salt Lake City. The athletes know that the noose is tightening. They will probably, I hope so, be more careful and wiser. But you can't guarantee that.

managing the cost and complexity of the games; putting athletes and sport at the heart of your bid; and on focusing on technical excellence, not on things which are not essential.

We would need to have guarantees in terms of immigration, of all athletes and all countries, to avoid this issue that we have with Cuba. These are things we need to have.

The Olympic Truce will not be eternal. After the games, bad habits will return. But this village is a perfect example of what the truce exemplifies. Here, athletes of different religions, political systems, races and languages live peacefully together.

The best athletes are not competing and the major athletes perform in an environment where doping controls are not what we have in the Olympic world.
