Chinese espionage in the United States

The United States has often accused the People's Republic of China (PRC) of unlawfully acquiring US military technology, classified information, personnel data, and trade secrets of US companies in order to support China's long-term military and commercial development. Alleged perpetrators include Chinese government agencies, affiliated personnel, civilian-in-name companies and their network of academic or business contacts.
