Chinese military specialist Li Jie told Global Times that China has many ways to respond if a U.S. aircraft carrier enters into the 12 nautical miles within China’s islands in South China Sea.
Li stated, “We don’t want to create trouble, but when the opponent challenges us, we should firmly counter back.”
Li said that in addition to the traditional warning, following, and driving away approaches, China now has more options. China can send an unmanned ship or drones to conduct close reconnaissance and to warn the ship, or it can use electromagnetic interference technology to interfere with the ship.
