A Chinese military spokesperson on Friday asked Japan to be discreet with its words and deeds on issues related to China's Taiwan region and the Diaoyu Islands.
Japan has ignored the basic norms of international relations, grossly interfered in China's internal affairs, deliberately hyped up the so-called "Chinese military threat," and made groundless accusations against China's legitimate maritime activities, said Tan Kefei, spokesperson for the Ministry of National Defense, in comments on contents in Japan's defense white paper 2021 regarding Taiwan and the Diaoyu Islands.
China has expressed its firm opposition and has lodged solemn representations with Japan, Tan added.
The Taiwan question is an internal affair of China, which allows no external interference, Tan said. The Diaoyu Islands and its affiliated islands are an inalienable part of China, and Chinese government ships' patrol and law enforcement activities there are lawful exercises regarding the country's sovereignty.
Tan said after the Second World War was over, the sovereignty of Diaoyu Islands was returned to China in line with international legal documents, including the Cairo Declaration and the Potsdam Proclamation.
