BEIJING - Chinese scholars warned Japan "must be locked into the 'cage' of international laws and its constitution," reacting to a series of Japan's recent breaches of its post-war security policy.

This July marks the 70th anniversary of the Potsdam Proclamation, a document issued by China, the United States and Britain on July 26, 1945 in demand of Japan's unconditional surrender in WWII and was accepted by Japan in the 1945 Japanese Instrument of Surrender.

However, in the same month, conservative forces in Japan represented by Abe's administration made the most significant overturn of its promise of a "purely defensive" military posture, a promise that Japan made at its surrender.

Japan's ruling coalition forced the passage of controversial security bills amid strong public opposition, which enables Japan to engage in wars overseas, posing a threat to the existing world order today.

Thus, at a press briefing held by the State Council Information Office on Thursday, scholars with Chinese Academy of Social Sciences (CASS) briefed the media about the Potsdam Proclamation terms and reiterated its important significance to the establishment and maintenance of the world order.
