Wu Yingzhuo, Dong Hao and Xia Lei conspired to hack private corporate entities to maintain unauthorised access to, and steal sensitive internal documents and communications from those entities' computers, federal prosecutors alleged.
For one victim, information that the defendants targeted and stole between December 2015 and March 2016 contained trade secrets, the Department of Justice said.
"Defendants Wu, Dong and Xia launched coordinated and targeted cyber intrusions against businesses operating in the United States, including here in the Western District of Pennsylvania, in order to steal confidential business information," said Acting US Attorney Soo C Song for the Western District of Pennsylvania.
Among the victims were Moody's Analytics, Siemens AG and Trimble.
The conspiracy began as early as 2011 and continued to May 2017.
