Taiwan's Ministry of National Defense (MND) said it tracked 10 Chinese military aircraft and six naval vessels around Taiwan between 6 a.m. on Tuesday and 6 a.m. on Wednesday, media reports said.

Of the 10 People’s Liberation Army (PLA) aircraft, four crossed the Taiwan Strait median line, according to the MND. Meanwhile, one Chinese drone entered the southwest corner of Taiwan’s air defence identification zone (ADIZ), while one PLA helicopter was tracked in the southeast sector of the ADIZ, reported Taiwan News.

Taiwan sent aircraft and naval ships and deployed air defence missile systems in response to monitor the PLA activity.

So far this month, Taiwan has tracked Chinese military aircraft 163 times and naval ships 96 times, the news portal reported.

 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 lead 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.

The question is why is Taiwan important to China?

“A lot of things actually, which of course are related to Taiwan but not necessarily direct to Taiwan. It's more about (China's) relationship changing with United States – or we should say Western Countries, mainly United States and China. Taiwan then happens to become key player and main actor in this dynamics,” said Alice.

100 miles from the coast of China, Taiwan is an island, that is located in the “first island chain,” this positioning makes it crucial to the US foreign policy.

US-Sino relations hinge on, ‘One China Policy,’ it acknowledges that, “there is only one Chinese Government." The US recognises its formal ties with China. With Taiwan the US shares independent strong “unofficial” relations.
