"The Chinese spy was charged with trying to steal US aviation trade secrets that could be used by Chinese entities to build the turbofan engine used in commercial jetliners without incurring substantial research and development expenses," the indictment released by the US Department of Justice had said.

India has developed Arihant, an ingenuously-built nuclear-propelled submarine that completed its first deterrence patrol recently, which is capable of firing ballistic missiles and can stay underwater for months. It has also acquired modern weapons from the USA like P8i. The P8i can detect underwater enemy submarines and also able to do maritime reconnaissances.
