In one case, a man is accused of intercepting flight communications near an airbase where US fighter jets are based, while in the other, information about military drills between US and South Korean forces was allegedly obtained. South Korea is a key ally of the US in Asia, and hosts its largest overseas military installation.
Both men have been charged with aiding an enemy state. In response to CNN’s request for comment, China’s Foreign Ministry said it was “not familiar with the situation.”
