China's armed forces conducted simultaneous military exercises to the west and east of Taiwan on Monday in a move analysts said was a warning to the self-ruled island and its supporter, the United States. The Chinese aircraft carrier Liaoning and its escorts were conducting maneuvers around Taiwan, China's military said in a statement Monday. "It was a routine training exercise organized according to the annual work plan to test the troops' training effectiveness and beef up their capability to safeguard national sovereignty, security and development interests," the statement said.
Meanwhile, at least 10 People's Liberation Army (PLA) warplanes, including four J-16 and four J-10 fighter jets, a Y-8 anti-submarine warfare aircraft and a KJ-500 early warning aircraft, entered Taiwan's self-declared air defense identification zone (ADIZ), according to Taiwan's Defense Ministry.
The US Federal Aviation Administration defines an ADIZ as "a designated area of airspace over land or water within which a country requires the immediate and positive identification, location, and air traffic control of aircraft in the interest of the country's national security."
