China says U.S. hacking accusations lack technical proof

BEIJING (Reuters) - Accusations by a U.S. computer security company that a secretive Chinese military unit is likely behind a series of hacking attacks are scientifically flawed and hence unreliable, China's Defence Ministry said on Wednesday.

The statement came after the White House said overnight that the Obama administration has repeatedly taken up its concerns about cyber-theft at the highest levels of the Chinese government, including with Chinese military officials.
