尖閣諸島問題
In July 2012, Chinese tabloid newspaper "Global Times" suggested that the central Beijing government should consider challenging Japan's sovereignty over Ryukyu Islands. The Chinese government has offered no endorsement of such views. Some Chinese consider that it is enough to support their independence, with professor Zhou Yongsheng warning that Ryukyu sovereignty issue will not resolve the Diaoyudao/Senkaku Islands dispute, and that "Chinese involvement would destroy China-Japan relations". Professor June Teufel Dreyer emphasized that "arguing that a tributary relationship at some point in history is the basis for a sovereignty claim ... [as] many countries had tributary relationships with China" could be diplomatically incendiary. Yasukatsu Matsushima, professor who advocates independence, expressed his fear of the possibility the Ryukyu independence would be used as a tool, and perceived Chinese support as "strange" since they deny it to their own minorities.
