Footage of a Chinese general discussing sensitive spying cases has been leaked onto Google Inc.'s video sharing site YouTube, in what appears to be an embarrassing failure of secrecy for the usually tightlipped military.

It wasn't clear when or where Maj. Gen. Jin Yinan made the comments and China's Defense Ministry did not immediately respond Monday to faxed questions about the video. Calls to the National Defense University where Jin is a lecturer rang unanswered.
