Kim Clijsters participated in a commercial to promote the China Open this week, although she recently said she would not play in Asia this fall due to worries about the radiation leaks from the Japanese nuclear reactors. The China Open, which is played in October, is a mandatory event on the WTA tour.

"The WTA is monitoring everything to see how it's going." Clijsters said. "But to me, if I decide to play or not play Beijing, it is because of the family situation, obviously. I don't like to go without Jada, but also don't want to take her for a one week trip to fly that long. Because obviously at that time we come back from the US Open and we have been gone for a long time, so she goes back to school. So there is a lot of things as a mother that make it sometimes a little bit tougher to choose my schedule."—Matthew Cronin
