China's Work Safety Record

I recently came across an article on bbc.com (http://news.bbc.co.uk/2/hi/asia-pacific/7213399.stm) discussing the attempted cover-up of the deaths of six construction workers. They were working on "The Nest," the new Olympic Stadium in Beijing. This looks poorly on China due to the fact they attempted to cover this up. I understand the hazardous conditions that come with working on constructions sites, but it makes me question China's commitment to take the necessary steps to provide safety for its workers, especially those on a national stage. I rarely hear about these sorts of tragedies happening in America, but many laws and regulations are in place to protect employees. I do not know if China is developing similar laws and regulations, but it seems very odd to me that they would not be practicing the highest safety standards when building the Olympic stadium.
