Japan cannot deny facts
In its bid to seize the Diaoyu Islands, Japan is trying hard to deny the historical facts that are to its disadvantage. Even its "power of administration" over the islands is a denial of the historical truth that the islands belong to China.
The islands and islets were Chinese territory until Japan forcibly seized them in 1895. The 1943 Cairo Declaration and the 1945 Potsdam Proclamation, which laid out the terms for the Japanese surrender at the end of World War II, obliged the country to return all the Chinese territories it had forcibly occupied.
However, the US administered the Diaoyu Islands after the war ended until June 17, 1971, when the US inked the Okinawa Reversion Treaty with Japan, which illegally handed the power of administration over the islands to Japan.
