China launched live-fire drills around Taiwan on Monday that it said would simulate a blockade of the self-ruled island's key ports, prompting Taipei to condemn Beijing's "military intimidation."

The drills "further confirm (China's) nature as an aggressor, making it the greatest destroyer of peace," Taipei's defense ministry said.

The Taiwan military said it had established a response center, deployed "appropriate forces" and "carried out a rapid response exercise."

Beijing claims Taiwan as part of its sovereign territory and has refused to rule out using military action to seize the island democracy.

When asked for comment on the drills by CBS News, the Pentagon said it has "nothing to offer on that." CBS News has also reached out to the White House for comment.

The latest show of force by Beijing follows the announcement earlier this month of a record package of arms sales to Taiwan of more than $10 billion by the United States, Taiwan's main security backer, and Japan's prime minister, Sanae Takaichi, saying its military could get involved if China were to move against Taiwan. But the Chinese military didn't bring up the U.S. or Japan in its statement Monday morning.

Beijing warned Monday that "external forces" arming Taipei would "push the Taiwan Strait into a perilous situation of imminent war," but didn't mention any countries by name.

Any attempts to stop China's unification with Taiwan would be "doomed to fail," foreign ministry spokesman Lin Jian told a regular press conference.

China said it was conducting "live-fire training on maritime targets to the north and southwest of Taiwan" in large-scale exercises involving destroyers, frigates, fighters, bombers and drones.

A military spokesman said earlier that Beijing would send army, navy, air force and rocket force troops for "major military drills" code-named "Justice Mission 2025."

The activities will focus on "sea-air combat readiness patrol, joint seizure of comprehensive superiority, blockade on key ports and areas, as well as all-dimensional deterrence outside the island chain," said Senior Colonel Shi Yi of the People's Liberation Army's Eastern Theater Command.

Chinese authorities also published a map of five large zones around Taiwan where further live-fire activities would take place for ten hours on Tuesday.

"For the sake of safety, any irrelevant vessel or aircraft is advised not to enter the afore-mentioned waters and airspace," the statement said.

China's drills will impact affect more than 100,000 passengers on scheduled international flights and about 6,000 on domestic flights Tuesday, Taiwan's transport ministry said Monday, according to the Reuters news service. Authorities will divert international flights from dangerous areas, the statement said.

Taiwan Presidential Office spokeswoman Karen Kuo condemned China's "disregard for international norms and the use of military intimidation to threaten neighboring countries."

Taipei said Monday it had detected four Chinese coastguard ships sailing off its northern and eastern coasts.

Its coast guard said it "immediately deployed large vessels to pre-position responses in relevant areas" and "sent additional support units."

Taiwan's defense ministry also said Monday it had detected a Chinese amphibious assault ship formation operating in the western Pacific. The ministry said it spotted 89 Chinese military aircraft -- the highest number in more than a year -- and 28 warships and coast guard vessels near Taiwan.
