TOKYO聽 鈥� Japan鈥檚 defense ministry said late on Friday it had spotted two Russian Navy ships in the waters near Taiwan and Japan鈥檚 Okinawa islands in the previous four days, following a similar announcement this week from Taiwan.
Taiwan鈥檚 defense ministry said on Tuesday it had spotted two Russian frigates off its eastern coast and send aircraft and ships to keep watch.
Japan鈥檚 government said last month that repeated Russian military activity near Japanese territory, including joint drills with Chinese forces, posed 鈥渟erious concern鈥� for Japan鈥檚 national security.
Japan and Taiwan have joined the United States and its allies in imposing wide-ranging sanctions on Russia after its invasion of Ukraine last year.
The Japanese ministry said two Steregushchy-class frigates were first spotted 70 km (40 miles) southwest of Japan鈥檚 westernmost island of Yonaguni, in Okinawa prefecture neat Taiwan, on Tuesday morning.
The vessels sailed back and forth through the waters between Yonaguni and Taiwan, moved eastward and were last spotted on Friday in the waters between Miyako and Okinawa islands, it said, adding Japan dispatched two vessels to monitor the Russian ships.
Russia鈥檚 Interfax news agency reported on Tuesday that a detachment of ships of the Russian Pacific Fleet had entered the southern parts of the Philippine Sea to perform tasks as part of a long-range sea passage.
