WASHINGTON (AP) — Evidence of an unrelenting campaign of cyberstealing linked to the Chinese government is prompting the Obama administration to develop more aggressive responses to the theft of U.S. government data and corporate trade secrets.

The Obama administration is expected to announce new measures Wednesday, including possible fines and other trade actions against China or any other country guilty of cyber-espionage. Officials familiar with the administration's plans spoke on condition of anonymity because they were not authorized to speak publicly about the threatened action.
Mandiant, a Virginia-based cybersecurity firm, released a torrent of details Monday that tied a secret Chinese military unit in Shanghai to years of cyberattacks against U.S. companies. Mandiant concluded that the breaches can be linked to the People's Liberation Army's Unit 61398.

Military experts believe the unit is part of the People's Liberation Army's cybercommand, which is under the direct authority of the General Staff Department, China's version of the Joint Chiefs of Staff. As such, its activities would be likely to be authorized at the highest levels of China's military.
