Japan looks into claim that China running

The government in Tokyo is investigating a report that China has set up covert police stations inside Japan, amid similar checks by authorities in European countries, the United States and Canada.
Safeguard Defenders, an Asia-focused rights group based in Spain, has published two reports since September alleging that Chinese authorities have established 102 overseas police stations in 53 countries, including Japan.
China has dismissed the allegations and on Thursday its foreign ministry denied that such police stations existed.
Asked about the Japanese government’s response to the report, Chief Cabinet Secretary Hirokazu Matsuno told a news conference: “We will take all necessary steps as we clarify the situation.”
Matsuno said Japan had told Chinese authorities that any activity that violated Japan’s sovereignty would be “unacceptable.”
