I have little or no faith in the IOC using their position for good, they seem to have become a mainly commercial enterprise more than willing to overlook the shameful nature of various governments approach to human rights . Sebastian Coe has been entirely useless in his response to various debates over the years, not just that of Peng.

I think the WTA's initial letter response was absolutely appropriate, but the WTA has been extremely happy to accept the vast sums that the Chinese part of the tour was bringing to them. So I'm sitting in my very cynical space about what's going on there.

But it's not just a tennis problem we can look at Formula 1 and Football and see how money has made so many bodies 'blind' to the many well documented concerns that surround the events.

I'd be happy to see all of these events be challenged and possibly disappear. It won't happen because of the amount of money involved, and that's where you have it.
Peng is one person in a debate with much money, politics and international status at stake.

I'm not as well informed as JonH (thanks for your post) but I feel very angry and concerned about how we somehow overlook our moral and ethical positions as long as we get a good match to watch.
