In the United States, the FBI arrested three Chinese citizens (Zhen Zhou Wu, Yufeng Wei and Bo Li) for trying to illegally export American electronic components that can be used in missiles, warplanes and space vehicles. The three are also accused of money laundering. Around the same time, in another incident, a Chinese scientist (Hong Meng ) working for Dupont, was accused of stealing technology for OLED flat screen displays, to use for perfecting similar technology being developed in China.
These incidents are just additional examples of China trying to steal foreign technology. The Chinese have been doing this in Japan and Europe as well, for decades. Russia got so fed up with this that they forced (via threats of litigation and economic pressure) the Chinese to sign a treaty, in which China agreed to stop the technology theft. This may slow the Chinese down, but it won't stop them.
