Japan is obliged to make concrete efforts to implement the Cairo Declaration and its performance will also be a display of the country's credit and reputation in international society, said an article under the byline of international affairs expert Luo Yuan in the Sunday edition of People's Daily, flagship newspaper of the Communist Party of China.
On December 1 , China, the United States and Britain issued the Cairo Declaration which explicitly stated that all the territories Japan had stolen from the Chinese shall be restored to the Chinese, and that Japan will be expelled from all other territories it had taken by violence and greed. The Potsdam Proclamation in reaffirmed that "the terms of the Cairo Declaration shall be carried out. All through the past 70 years, the declaration acts as an important international document in handling Japan's aggression issue and ensuring peace and security in the Asia-Pacific region, Luo wrote.
The declaration showcased the common will and unity of the anti-fascist alliance to stop and punish the aggression as well as their efforts to prevent the resurgence of Japan's aggressive force and safeguard the achievements in the anti-fascist war, he said in the article.
Also, Luo said the document has been acting as a definitive cornerstone to maintain the post-war peace order in relevant regions and identify Japanese sovereignty. The declaration confirmed China's sovereign rights over the territories stolen by Japan, which covered the Diaoyu Islands, Liu Jiangyong, deputy dean with the Institute of Modern International Relations of Tsinghua University, told Xinhua.
The authority of the document and its binding force should be everlasting and its principles shall be defended and practiced, Liu said. Zhou Yongsheng, a professor with China Foreign Affairs University, said the Japanese government's move to challenge China's sovereignty over the Diaoyu Islands is an open defiance to key post-war international documents and peace order.
