Russian Scientist Accused of Betraying Hypersonic Secrets to China and Deceiving Putin.

The director of Russia's Khristianovich Institute of Theoretical and Applied Mechanics (ITAM), Alexander Shiplyuk, has been accused of betraying secrets to China at a scientific conference in 2017, according to sources. Shiplyuk, along with two other hypersonic missile technology experts, was arrested on suspicion of treason last August. The 56-year-old maintains his innocence and insists the information in question wasn't classified and was freely available online. The Chinese connection would make Shiplyuk the latest in a string of Russian scientists who have been arrested in recent years for allegedly betraying secrets to Beijing.
