Recently, anti-Japanese demonstrations in China have brought Sino-Japanese relations to their lowest point in decades. China believes that the Japanese government's whitewash of its wartime atrocities in China in its high school textbooks and Japanese Prime Minister Junichiro Koizumi's visits to the Yasukuni Shrine indicate that Japan is eager to return to nationalistic militarism.
China also regards disputes over the sovereignty of the Tiaoyu islands and the US-Japan security alliance's move to publicly identify Taiwan as a joint security concern as attempts to encircle China. As for Japan, it believes that its revised history textbooks and Koizumi's shrine visits are purely domestic affairs, and also a first step toward making Japan a normal nation. The Tiaoyu islands dispute and the US-Japan Joint Declaration on Security identifying security in the Taiwan Strait as a "common strategic objective," in Japan's view, represent a shift from a passive to an active posture in national defense policy.
