Japan’s coastguard was on high alert on Wednesday, a year to the day since Tokyo nationalised islands at the centre of a bitter dispute with China.
Relations, which have often been testy, have soured dramatically over the last 12 months, with frequent confrontations between official ships from Asia’s largest powers.
On Tuesday, Tokyo said it had not ruled out stationing officials there, drawing a response from Beijing, which warned Japan “must be prepared to bear the consequences of this provocation”.
“We are on high alert as today marks the first anniversary of the nationalisation of the Senkaku islands,” coastguard official Yuma Miyako said, referring to the Tokyo-controlled islands claimed by China as the Diaoyus.
Since last September, official Chinese vessels have regularly traversed the waters - China said on Tuesday it had carried out 59 “patrols” - each time being warned off by their Japanese opposite number, and the two nations’ militaries have shadow-boxed in international waters and international skies.
Tokyo says it nationalised the islands as a way to take the sting out of a potentially explosive attempt by nationalists to buy them, with talk of developing them for tourism.
