Tokyo says it has conveyed an โappropriate messageโ to Beijing over vesselsโ movements.
Two Chinese aircraft carriers have been seen operating in the Pacific at once for the first time, Japanโs Ministry of Defence has said.
Chinaโs Shandong and four other vessels on Monday sailed within Japanโs exclusive economic zone (EEZ), the Defence Ministry said on Tuesday.
The aircraft carrier conducted landing and takeoff drills involving its fighter jets and helicopters in waters north of the Pacific atoll of Okinotori, the ministry said.
Tokyoโs announcement came a day after Japanese officials said the Liaoning, the older of Chinaโs two operating aircraft carriers, had entered waters near the remote island of Minamitorishima.
Japanese Chief Cabinet Secretary Yoshimasa Hayashi said Tokyo would step up surveillance and had conveyed โan appropriate messageโ to China, without elaborating.
On Monday, Hayashi, who is Tokyoโs top spokesman, said Chinaโs growing maritime activity appeared to be aimed at bolstering its capability to carry out missions farther from its shores.
Chinese Foreign Ministry spokesman Lin Jian on Monday defended the aircraft carriersโ movements, describing them as โfully consistent with international law and international practicesโ.
โOur national defence policy is defensive in nature. We hope Japan will view those activities objectively and rationally,โ Lin told a regular news conference.
