On Tuesday morning Osamu Fujimura, Japan’s chief cabinet secretary, confirmed his country had agreed to purchase the islands, called Senkaku in Japan and Diaoyu in China, from a Japanese family it claims owns them.
Media reports in Japan said the government would pay a total of 2.05 billion yen (£16.4 million) for the islands and that the transfer of their ownership would be completed by the end of this month.
Simultaneously, China’s state-controlled news agency Xinhua reported that two Chinese surveillance vessels had arrived in the region on Tuesday to “assert the country’s sovereignty”. Japanese media said the Japanese Coast Guard was monitoring the vessels.
