Japan protests to China over sub

BBC News

Japan has summoned a senior Chinese diplomat to issue a formal protest over a submarine spotted inside its waters earlier this week.
Japan earlier said it was sure the submarine was Chinese because of its type and apparent direction.

Japan's navy was put on alert for the first time in five years to chase it.

The incident is likely to further raise tensions between Japan and China, already locked in disputes about contested islands and gas fields.


"We made a strong protest and demanded an apology," Japanese Foreign Minister Nobutaka Machimura said after meeting Chinese embassy official Cheng Yonghua. China's ambassador to Japan was reportedly out of Tokyo.
