Chinese operational behavior in the waters around the small group of islands under Japanese administrative control known as Senkaku, and claimed by Beijing under the name Diaoyu, has entered a new, dangerous phase. In an unprecedented move, Chinese coast guard cutters in early July started to operate inside the islands’ territorial waters in a fashion that would suggest Beijing is there to exercise law-enforcement powers. It appears China no longer seeks to just showcase its “presence” in the waters around the islands. It is now starting to actively challenge Japanese control.
