Tensions with China have worsened over the past 40 years, the Taiwanese defense minister said, warning of the dangers of an accidental strike between the two.
Chiu Kuo-cheng’s comments came after China sent a “recorded number” of military aircraft to airstrip in Taiwan for four consecutive days.
Taiwan considers itself to be an independent state. China, however, views Taiwan as a rebel province.
It does not rule out the possible use of force to achieve unity.
Mr Chiu also warned that China would be able to completely invade the island by 2025.
He was speaking while a parliamentary committee in Taipei was considering a multi-billion-dollar bill to build missiles and warships.
Announcing that China already has the potential to attack, he said such action would be easier in the coming years, although he did not elaborate.
Taiwan separated from the continent as the communists took power in 1949.
However, the agreement also allows Washington to maintain “robust and unofficial” relations with Taiwan. The United States sells arms to Taiwan as part of Washington’s Taiwan Relations Act, which states that the United States must help Taiwan defend itself.
The “One China” policy, which Mr. Biden and Mr. Xi are believed to refer to, is the cornerstone of Sino-US relations but differs from the One China policy, in which China emphasizes that Taiwan is an undeniable part of a single China merger one day.
