The Eastern Theatre Command said the Just Mission 2025 drills will involve live-fire exercises on Tuesday, in a statement containing a graphic demarcating five zones surrounding the island that will be under sea and air space restrictions for 10 hours.
This marks China's sixth major round of war games since 2022 after then-US House Speaker Nancy Pelosi visited the self-governed island, and follow a rise in Chinese rhetoric over Beijing's territorial claims after Japanese Prime Minister Sanae Takaichi suggested a hypothetical Chinese attack on Taiwan could trigger a military response from Tokyo.
"This (the drills) serves as a serious warning to 'Taiwan Independence' separatist forces and external interference forces," Shi Yi, a spokesperson for China's Eastern Theatre Command said in a statement.
"The exercise focuses on training for maritime and aerial combat readiness patrols, gaining integrated control, sealing off key ports and areas and conducting multi-dimensional deterrence."
The military released a poster titled Shields of Justice: Smashing Illusions, featuring two golden shields emblazoned with the Chinese People's Liberation Army insignia and the Great Wall of China, along with three military aircraft and two ships.
Taiwan's defence ministry did not immediately respond to a request for comment.
While the PLA had carried out port blockades around Taiwan during war games last year, this marks the first time it has publicly stated that drills around the island are aimed at "deterrence" of outside military intervention.
The drills began 11 days after the US announced $US11.1 billion ($A16.5 billion) in arms sales to Taiwan, the largest ever weapons package for the island, drawing a protest from China's defence ministry and warnings the military would "take forceful measures" in response.
Taiwan, an island off the southeastern coast of China, separated from the mainland in 1949 amid Civil War. It has operated since then with its own government, though the mainland's government claims it as sovereign territory.
