Almost a quarter of Japanese manufacturers are rethinking their investment plans in China and some may shift future production elsewhere after the spike in tensions between Asia's two largest economies.

The sentiments were expressed in a Reuters Corporate Survey released on Wednesday and in interviews conducted in recent weeks with executives in industries ranging from electronics to apparel manufacturing.

The concerns suggest the recent rift between China and Japan over disputed islands in the East China Sea could mark the end of a boom that has played out over two decades in which Japanese companies have emerged as the most active source of outside direct investment in China after Hong Kong and Taiwan.
