Footage of a Chinese general discussing sensitive spying cases has been leaked onto 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 major general Jin Yinan made the comments.
While some of the cases had been announced before, few details had been released, while others involving the military had been entirely secret.Among those Jin discussed was that of former ambassador to South Korea Li Bin, who was sentenced to seven years for corruption.
Jin said Li had actually been discovered passing secrets to South Korea that compromised China's position in North Korean nuclear disarmament talks, but the allegations were too embarrassing to make public and graft charges were brought instead.
"In all the world, what nation's ambassador serves as another country's spy?" Jin said.
Similar treatment was handed out to the former head of China's nuclear power program, Kang Rixin, who was sentenced to life in prison last November on charges of corruption.
Jin said Kang had in fact peddled secrets about China's civilian nuclear program to a foreign nation that he did not identify, but that was considered too sensitive to bring up in court.
Kang, a member of the ruling Communist Party's powerful Central Committee as well as its disciplinary arm, was one of the highest-ranking officials ever to be involved in spying, Jin said. His arrest dealt a major shock to the party leadership, Jin said.
The video was also posted on Chinese websites, and while it was removed from most locations, screen shots, audio files and transcripts of Jin's comments could still be found on sites such as Sina Weibo's popular microblogging service.
