China sends aircraft, vessels toward Taiwan days after US arms sale approval
China sends aircraft, vessels toward Taiwan days after US arms sale approval
As many as 20 aircraft from China either crossed the median line of the Taiwan Strait or breached the island country’s air defense identification zone.
A "median line" exists within the Taiwan ADIZ, an unofficial demarcation between People's Republic of China (China) and the Republic of China (Taiwan) airspace. The Taiwan ADIZ includes a large portion of the Chinese mainland.

Although the ADIZ covers parts of China's Fujian and Zhejiang provinces in its northwestern part, PLA flights in those areas are not reported as incursions unless they flew within the 12-mile territory limit or median line between the outer islands controlled by ROC forces and mainland China.

Here's the source on Taiwanese ADIZ, as well as what parts of Taiwanese ADIZ are accepted by the US (and thus, what the US will report on): https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://digital-commons.usnwc.edu/cgi/viewcontent.cgi%3Farticle%3D2939%26context%3Dils&ved=2ahUKEwiGoKKS3PqAAxXDD0QIHYVzDg0QFnoECBAQAQ&usg=AOvVaw0FmfTWzQ9XNfwfTL-qwUs5
Notably, Taiwan's ADIZ that crosses over mainland China is not recognized by the US, BUT, US recognition of Taiwan's ADIZ is neither at the median line nor at Taiwan's 12-mile territory limit. This is clearly visible in the middle and northwestern corners of where the US recognizes Taiwan's ADIZ, which, as you will note, are not at the median point between the two bodies.
