evidence: September 11 will mark the 10th anniversary of the Japanese government purchase of the Senkaku Islands (specifically, Uotsuri Island, Minamikojima Island and Kitakojima Island) from their previous owners. [...] Japan responds to the entry of CCG vessels into the territorial waters around the Senkaku Islands by demanding that CCG vessels – which claim that they are engaged in law enforcement activity in accordance with Chinese domestic laws and regulations – to withdraw on the basis of the United Nations Convention on the Law of the Sea (UNCLOS). [...] Japan and China disagree on the territorial sovereignty of the Senkaku Islands (known in China as the Diaoyu Islands), with differences that are not easy to reconcile. The Japanese government does not recognize the existence of any international dispute over the territorial sovereignty of the islands. It is important that Japan manages the different opinions of Japan and China by gradually attenuating the confrontations in the surrounding waters through diplomatic means, while simultaneously ensuring that confrontations do not escalate into clashes.
