A Chinese worker scratches his head as pictures of China's late chairman Mao Zedong (C) and late paramount leader Deng Xiaoping (R) loom in the background in Beijing April 20. Chinese authorities, expecting more state enterprises to go bankrupt after Beijing's entry to the World Trade Organisation (WTO), are eager to establish efficient measures and improve China's social security system to ensure that laid-off workers get the full amount of living expenses in order to secure social stability. Since 1996, the number of workers laid off by the state enterprises has exceeded 30 million.
