The PLA Eastern Theater Command has successfully completed the military drills code-named "Justice Mission 2025," and has fully tested the integrated joint operations capabilities of its troops, Senior Captain Li Xi, spokesperson of the PLA Eastern Theater Command, announced on Wednesday.

The troops of the theater command will keep strengthening combat readiness with arduous training, resolutely thwart the attempts of secessionists in Taiwan and external intervention, and firmly safeguard national sovereignty and territorial integrity, he said.

The exercises, which started on Monday, involved Army, Navy, Air Force and Rocket Force units operating in the Taiwan Strait and waters to the north, southwest, southeast and east of Taiwan Island.

The latest military drills conducted by the PLA around the island were a stern warning to "Taiwan independence" separatist forces and external interference, said Zhang Han, a spokesperson for the State Council's Taiwan Affairs Office, at a press conference on Wednesday.

They were a necessary and just move to defend national sovereignty and territorial integrity, she added.
