FWiW :
The Republic of China (ROC), or simply China, was a sovereign state based in mainland China from 1912 until its government's retreat in 1949 to Taiwan, where it is now based.
The nine-dash line, also referred to as the eleven-dash line by Taiwan, is a set of line segments on various maps that accompanied the claims of the People's Republic of China (PRC, "mainland China") and the Republic of China (ROC, "Taiwan") in the South China Sea.
A 1946 map showing a U-shaped eleven-dash line was first published by the Republic of China government on 1 December 1947.
The area has always been claimed, whether by the ROC, the PRC, or indeed under Puyi, who had reigned as the Xuantong Emperor of the Qing dynasty.
The issue is that "Western" sea faring nations self selected themselves as arbitrators of global borders, including those of regions with governance dating back 4,000 years.
On 12 July 2016, an arbitral tribunal organized under the United Nations Convention on the Law of the Sea (UNCLOS) concluded that China had not exercised exclusive and continuous control over the [ dashed zones ]
Over 20 governments have called for the ruling to be respected.
It was rejected by eight governments, including China (PRC) and Taiwan (ROC).
It is somewhat disingenuous to say that Taiwan claims those regions. China has made it clear that any abdication of those claims would be seen as a move towards independence and result in invasion.
Similar to the Chinese claims that the British never brought democracy to HongKong while China threatened invasion if any such thing had happened.
