Tensions Rise between China and Japan over Senkaku / Diaoyu

It seems inconceivable that we might see the return of military conflict between China and Japan. However, as this video from the FT explains, there is increasing tension between China and Japan focused on a disputed island chain known as Senkaku in Japan and Diaoyu in China.

With China displaying its increasing military muscle both on land and at sea, and Japan's prime minister Shinzo Abe seeking to loosen the terms of the country's anti-war constitution, the FT's Dmetri Sevastopulo says that the chance of an accidental confrontation escalating is increasing.
