China’s brusque treatment of Japan’s leaders probably was intended as a rebuke not only over the Senkaku Islands issue, but also for hosting the Fourth General Meeting of the World Uyghur Congress in Tokyo in May. Previously, such meetings had been held in Germany and the United States, and this one, which stressed the importance of protecting human rights and preserving the traditions, culture, and language of the Uyghur people, received no official sanction or endorsement from the Japanese government.
中国之所以对日本领导人唐突以待，恐怕不仅仅是在钓鱼岛问题上的示威，也是在对5月第四届世界维吾尔大会在东京召开表示不满。此前，世界维吾尔大会曾在德国和美国举行，而此次在日本召开的第四届大会旨在强调保护人权，捍卫维吾尔族的传统、文化和语言，日本政府对此既不反对，也不赞成。
