We will do our utmost to show our commitment in the fight against doping. We plan to have the most ambitious and comprehensive system of testing ever activated at a world championships.

We'll literally have the world's best athletes here in Osaka. This will be a good opportunity for young Japanese athletes to see what the world is like.

I am delighted to see such strong interest from so many different parts of the world.

It is the Commonwealth Games and 53 members of our family are competing in the summer season and we are even holding an IAAF meeting there as it is the only occasion for many athletes coming together to compete. (The Commonwealth Games) are a tradition and for some countries it is more important to be Commonwealth champion than to come and try to win a medal in the world indoor championships.

This is a landmark CAS decision and one that the IAAF welcomes as it continues to pursue its anti-doping fight with the utmost vigor.
