Ukraine's counterintelligence service (SBU) arrested a Chinese father and son on suspicion of spying on its Neptune anti-ship missile program, a key part of Kiev's growing domestic arms industry that is critical to its defense against Russia. Although Beijing tries to project an image of neutrality, they are helping the Kremlin's war effort. SBU agents arrested a 24-year-old former student in Kiev after they provided him with "technical documentation" related to Neptune production. CI agents later detained his father, who had aimed to smuggle out the documents to the Chinese MSS. The father had been living in China but visited Ukraine to "personally coordinate" his son's work. Since Russia's brutal full-scale invasion in 2022, Ukrainian forces have captured Chinese nationals fighting for Russia on the battlefield, but these two men were the first arrested in Ukraine on espionage charges.
