TOKYO - A Chinese navy reconnaissance vessel briefly entered Japan's territorial waters early Wednesday off the southwestern prefecture of Kagoshima, a Japanese government spokesman said.
Deputy Chief Cabinet Secretary Hiroshige Seko said the vessel had been spotted by a Japanese patrol plane around 3:30 a.m. local time and that it had left around 5 a.m.
"The government will continue to take all possible measures for warning and surveillance activity for our territorial waters and airspace," Seko told a news conference.
