When the world's greatest athletes arrive in Beijing, China for the 2008 Summer Olympic Games, the focus will shift to international competition. In the meantime, it's on smog, human rights and international politics. Recently, Stephen Spielberg resigned as the Games' artistic advisor, claiming that China is not doing enough to make peace in Darfur. Human rights groups say political dissidents are being rounded up by a government that promised to allow greater freedom of speech. Coaches worry about the health of their athletes, not to mention the Chinese people, despite the pledge to clean up the air. Looking forward to the greatest sports event in the world, we'll hear about smog, human rights and international politics.
