evidence: After the 1978 treaty, tension sparked again in 1992 as the Chinese government explicitly included the Diaoyu/Senkaku Islands as a part of "the territorial sea of the People’s Republic of China", prompting Japanese objection.[12] More recently in 2010, a collision incident between a Japanese Coast Guard ship and a Chinese civilian fishing ship in the disputed waters and the subsequent Japanese arrest of the Chinese civilian resulted in an increase in anti-Japanese sentiment in China.[13] Diplomatically, China canceled scheduled ministerial meetings with Japan.[14]However, possibly the most controversial incident was the Japanese nationalization of the islands. In an effort to thwart the conservative Tokyo Governor’s plan to purchase and develop the islands, the Japanese national government made the purchase instead in order to leave the islands undeveloped.[15] Ironically, the decision that was intended to minimize diplomatic repercussions prompted the Chinese government to publish "Diaoyu Dao, an Inherent Territory of China", a white paper delineating the Chinese official position on the territorial dispute.[16] [...] [17] ""Diaoyu Dao, An Inherent Territory of China" White Paper"; "Senkaku Islands Q&A".
