Contemporary Sino-Japanese relations have long crossed the line from foreign policy to becoming an active domestic issue, particularly in China and now increasingly so, also in Japan. China appears to believe both that nationalist passions can be controlled and that time and demography are on its side. The first assumption is questionable though evidence till now shows that Beijing has been successful while the second is correct. India will then have to manage its relationship with Japan keeping both realities in mind.
Given their long history of exchanges, it was always unlikely that the legacy of World War II would be forgotten or forgiven as in the European case but in both countries this past is now being used to rake up and create fresh reasons for discord and enmity. In China, the humiliation of being overrun and subject to the depredations of the Japanese was the worst of the ‘century of humiliations’ while for the Japanese, their brief dominance over China allowed them to finally emerge from the long historical and civilizational shadow of their larger neighbour.
