Is the bankrupt Pingguo Aluminum a state-owned enterprise?

The bankrupt Pingguo Aluminum is a state-owned enterprise. Because Pingguo Aluminum Industry is a super-large aluminum smelting joint venture jointly established by the former China Nonferrous Metals Industry Corporation and the People's Government of Guangxi Zhuang Autonomous Region, it is a key construction project during the Eighth Five-Year Plan period. Although the enterprise has gone bankrupt, its history and background show that it was a joint venture between China and the people's government of Guangxi Zhuang Autonomous Region, so it is still called a state-owned enterprise by some people.
