"On Sept. 10 [2012], the Japanese government announced to "purchase" the Diaoyu Islands and its affiliated islets, officially implementing the so-called "nationalization." This is a farce under the background of the United States' return to Asia-Pacific strategy. Japan took advantage of the United States' commitment of "helping defend the Diaoyu Islands" to embolden itself. Meanwhile, it is also Japan's active collaboration with the United States' strategy of "return to Asia-Pacific" to contain the peaceful rise of China." (Quoted from article)
