Chinese carrier holds air drills as Tokyo, Beijing trade barbs

TOKYO - A Chinese carrier strike group launched intense air operations near Japan over the weekend as the East Asian neighbors traded diplomatic barbs in an escalating dispute, further straining ties.

The encounters in waters close to Japan’s southwest island chain come after Prime Minister Sanae Takaichi warned last month that Tokyo could respond to any Chinese military action against Taiwan that also threatened Japan's security.

On the weekend, China's Liaoning aircraft carrier conducted about 100 take-offs and landings as it sailed east into the Pacific Ocean past the Okinawa Islands, Japan's Self-Defense Forces said on Monday.

Tokyo summoned China's ambassador, Wu Jianghao, on Sunday to protest behaviour it called dangerous and regrettable after saying the carrier's fighter jets aimed radar beams at its aircraft scrambled to shadow the vessel the previous day.

Illuminating aircraft with a radar signals a potential attack that may force targeted planes to take evasive action.

The Chinese embassy denied Tokyo's claims, saying Japanese aircraft had endangered flight safety by approaching the Liaoning as it trained with three missile-destroyer escorts.

"China solemnly demands that Japan stop smearing and slandering, strictly restrain its frontline actions, and prevent similar incidents from happening again," the embassy said in a statement.

Chief Cabinet Secretary Minoru Kihara rejected China’s claim that Japan’s aircraft had obstructed safe flight operations.

Japan will "respond calmly but firmly and continue to monitor the movements of Chinese forces in the waters around our country," he told a regular press briefing.

Takaichi's comments prompted Beijing to advise citizens not to travel to Japan. It also paused a restart of seafood imports suspended after Japan released treated water from the crippled Fukushima nuclear plant.

China claims democratically governed Taiwan and has ramped up military and political pressure against the island, whose government rejects Beijing's territorial claims.

A former Japanese colony, Taiwan lies just 110 km (70 miles) from its westernmost island in the southwest Okinawa chain.

Japan hosts the biggest overseas concentration of U.S. military power including thousands of U.S. Marines in Okinawa.

The U.S. State Department and the U.S. embassy in Tokyo did not respond to requests for comment on Japan's claims about China's use of its radar.

The U.S. ambassador to Japan, George Glass, has voiced support for Japan in the dispute with China, although President Donald Trump, who plans to travel to Beijing for trade talks next year, has kept silent.
