Image caption Experts believe Japan's warship could support fighter jets in the future

Media in China are warning against Japan's "remilitarisation" after the country unveiled its biggest warship since World War II on Tuesday.

The huge Japanese flat-top destroyer, Izumo, has a flight deck nearly 250m (820ft) long and can reportedly carry more than nine helicopters.

The Liberation Army Daily and many Chinese military experts are calling the new-generation 22DDH helicopter carrier a "quasi-aircraft carrier" in disguise.

They believe that it could be refitted to support fighter jets if Japan's post-war pacifist constitution is changed in the future.

The vessel is also raising eyebrows in China Daily since it is the "same name as the flagship of the Japanese fleet that invaded China in the 1930s".

"This is yet another 'edge ball' played by the Japanese government... China can only respond to 'Izumo', this light aircraft carrier dressed as an 'escort vessel', by developing a real aircraft carrier," stresses the Global Times.

Despite Japanese Prime Minister Shinzo Abe's decision not to visit the Yasukuni Shrine on 15 August - the day of Japan's surrender in World War II - some media criticise him for not stopping politicians from paying visits.

The Tokyo shrine honours Japan's war dead, including military leaders convicted of war crimes in WWII.

"Japanese politicians should lay the 'ghost worship' farce to rest! 15 August is the anniversary of the people of Asia getting rid of the ravages of Japanese militarism," says the People's Daily.

Selling babies

Elsewhere, The Beijing News says more families have come forward saying that a hospital doctor in Shaanxi province tricked them into giving up their newborn babies.

The allegations come amid an ongoing investigation into an obstetrician in Shaanxi province who allegedly tricked parents into giving up their newborn boy and then sold him to human traffickers. Health authorities have ordered a nationwide review of hospitals.

In other news, many media are concerned over the integrity of China's judiciary following the expulsion of four senior judges and a state-owned company executive in Shanghai from the ruling Communist Party for allegedly soliciting prostitutes at a hotel resort nightclub in June.

"If a judge is not honest, it will be impossible to have clean courts and clear justice," concludes the Yanzhao Metropolis Daily.

The Beijing Morning Post echoes widespread public anger at two justice bureau officials in Jiyuan, Henan, who reportedly stayed in an air-conditioned car and refused to help a woman who had been knocked down.

As the debate over political reform heats up, the People's Daily has launched another attack on the concept of constitutional checks on a government's power by recalling how liberalisation brought about the collapse of the Soviet Union.

"China engaging in so-called constitutionalism can only be as futile as climbing a tree to catch a fish," a front-page commentary in its overseas edition warns.

And finally, another former Red Guard has expressed public remorse for violence committed during the Cultural Revolution (1966-1976), when many young people were encouraged to denounce and even beat their parents and teachers.

Zhang Hongbing, formerly Zhang Tiefu, tells The Beijing News how he is still tormented by his calls for his mother to be shot as a "counter-revolutionary" for criticising Chairman Mao. He was only 16 when he witnessed her being publically executed.

Mr Zhang speaks of his frustration at how authorities turned down his request for his mother's grave in their hometown of Guzhen in central Anhui province to be made a heritage site.
