China yesterday blamed Japan for the renewed tensions over the disputed Diaoyu Islands. A day after a failed landing attempt by Hong Kong and Taiwanese activists, Beijing said Japan had not done enough to avoid a showdown with the protesters. Foreign Ministry spokesman Shen Guofang stopped short of endorsing the activists' actions, but said: 'The Japanese Government has encouraged nationalists to land on the islands. The responsibility rests entirely with Japan. 'We hope the Japanese will adopt truly effective measures and not provoke new incidents.' The latest protests over the islands, which are claimed by Japan, China and Taiwan, were sparked by last month's landing by a Japanese MP. China's comments came as 18 Hong Kong activists arrived back in the territory, vowing to carry out more protests against the Japanese Government. Committee commander Albert Ho Chun-yan described their failed landing as a 'glorious' defeat, but denied their boat had rammed a Japanese patrol vessel. 'The campaign to protect Diaoyus will not end,' he said. 'We shall continue our protests until the Japanese get out. But we may review our strategy.' Mr Ho claimed film of his boat Diaoyu Tai ramming the Japanese launch had been heavily edited and was misleading. The Diaoyu Tai, which will return to Hong Kong from the Taiwanese port of Keelung after repairs, was one of about 20 protest boats which sailed to the islands. Japan sent 60 coastguard vessels to repel the flotilla. The Marine Department is not expected to investigate the alleged ramming. A department spokesman said yesterday that the Diaoyu Tai, which is expected back in the territory in a couple of days, was a licensed pleasure boat and under existing regulations it had no authority to investigate its activities outside Hong Kong waters.
