Show Notes
It’s an open secret that the Chinese government has engaged in a global campaign to acquire intellectual property from foreign rivals. At the center of that campaign is the Ministry of State Security, China’s elusive intelligence agency. The US has apprehended hundreds of people accused of giving information to the MSS, but the agency’s inner workings have been a mystery — until now.
Today, we’re bringing you Episode 1 of The Sixth Bureau, a limited-run series from The Big Take. The series follows an MSS intelligence officer whose mission was to acquire the crown jewels of American aerospace companies. With aliases, blackmail and the occasional break-in, he targeted corporate giants. That is, until his sloppiness — and a cunning FBI sting — led to a stunning reversal: Xu Yanjun became the first Chinese intelligence officer ever convicted on American soil.
