Taiwan government detect 47 sorties by Chinese aircraft, seven vessels

The Taiwanese government has detected 47 sorties by Chinese aircraft and seven vessels until 6 pm local time on Saturday.
Taiwan's Ministry of National Defence claimed 41 crossed the median line and entered Taiwan's northern, southwestern and eastern ADIZ.
In an X post, the Ministry posted: "47 PLA aircraft, 7 PLAN vessels and 1 official ship operating around Taiwan were detected up until 6 a.m. (UTC+8) today. "
The Ministry said: " 41 out of 47 sortie crossed the median line and entered Taiwan’s northern, southwestern and eastern ADIZ. We have monitored the situation and responded."
What is the basis of China’s claim over Taiwan?
The basis of China’s claim over Taiwan dates back to 1945 when Japan lost its control over the island in 1945,post-World War Two.
The 1949 Chinese civil war led to communists taking control and Chiang Kai-shek the one who lost fled to Taiwan.
He ruled it for many decades.
This is where China’s claim to Taiwan emanates. The very fact that Chiang Kai-shek came to Taiwan and was not indigenous to the place is Taiwan’s argument against the claim.
