The Eastern Theater Command of the Chinese People's Liberation Army (PLA) on Monday successfully completed all tasks of combat readiness security patrol encircling the Taiwan Island and "Joint Sword" exercise.

In a statement issued on Monday evening, Shi Yi, spokesperson for the command, said the integrated joint operational capabilities of different PLA services and branches under realistic combat scenarios had been comprehensively tested during the drills, which took place from Saturday to Monday.

When announcing the operations on Monday, Shi said they served as a stern warning against the collusion between separatist forces seeking "Taiwan independence" and external forces and against their provocative activities.

The PLA practiced seizing control of sea, air and information on Saturday, and carried out simulated joint precision strikes on key targets on the island of Taiwan and in its surrounding waters on Sunday.

The Shandong aircraft carrier group joined Monday's drills. In a video broadcast by China Central Television, a J-15 carrier-borne fighter jet is seen taking off from the deck of the aircraft carrier.

During the exercises, several destroyers and frigates conducted suppressive combat patrol missions, as they carried out training courses including assaults on fleeing hostile vessels and maritime blockade.

Zhang Benming, an officer with the unified command of the PLA Eastern Theater Command, said the military services advanced the "all-weather and multi-directional" encircling of the island of Taiwan, comprehensively testing their ability of command control, precision strike and three-dimensional blockade supported by the unified command system.

Zhang said that the command troops will prepare for and be ready for battle at all time, and crush any kind of "Taiwan independence" secessionist or external interference attempts.
