China holds low-key Nanjing Massacre memorial without Xi amid Japan row 

China has held a low-key memorial ceremony for the Nanjing Massacre, as a diplomatic crisis between Beijing and Tokyo over Taiwan continues to simmer.

President Xi Jinping did not attend the ceremony on Saturday commemorating the 1937 attack, in which China says Imperial Japan’s troops slaughtered 300,000 people in the eastern city of Nanjing.

A post-World War II Allied tribunal put the death toll at 142,000, but some conservative Japanese politicians and scholars have denied that a massacre took place at all. China and Japan have long sparred over their painful history.

Japanese Prime Minister Sanae Takaichi has infuriated Beijing after her remarks last month in which she projected that a hypothetical Chinese attack on the self-governed island of Taiwan could trigger a military response from Japan.

Doves flew over the national memorial centre in Nanjing after the ceremony, which was completed in less than half an hour, in front of an audience that included police officers and schoolchildren.

Shi Taifeng, head of the ruling Communist Party’s powerful organisation department, made far less combative remarks than recent rhetoric from Chinese government officials.

“History has proven and will continue to prove that any attempt to revive militarism, challenge the post-war international order, or undermine world peace and stability will never be tolerated by all peace-loving and justice-seeking peoples around the world and is doomed to fail.”

He did not mention Takaichi but alluded to China’s previous assertions that the Japanese leader seeks to revive the country’s history of militarism.

On Saturday, the Eastern Theatre Command of China’s People’s Liberation Army put out a picture on its social media accounts of a large bloody sword, of the type used by many Chinese soldiers during the war, chopping off the head of a skeleton wearing a Japanese army cap.

“For nearly 1,000 years, the eastern dwarves have brought calamity; the sea of blood and deep hatred are still before our very eyes,” it said, using an old expression for Japan.

Last month, Japan’s Defence Minister Shinjiro Koizumi announced that Tokyo was moving forward with plans to deploy a missile system on Yonaguni, the country’s westernmost island located 110km (68 miles) off Taiwan’s east coast, which has hosted a Japanese military base since 2016.

China’s Ministry of Foreign Affairs blasted the announcement, describing Japan’s plan as a “deliberate attempt to create regional tension and provoke military confrontation”. Koizumi pushed back, saying the Type 03 guided missile system was purely defensive and “intended to counter aircraft and missiles invading our nation”.

Beijing views Taiwan as its own territory and has promised to unite the island with the Chinese mainland, an aspiration that Taipei says infringes on its sovereignty and that only Taiwan’s citizens can decide their future.

Both countries have since traded quarrelsome accusations, with Japan summoning China’s ambassador earlier this month over an incident in which Chinese military aircraft allegedly twice locked fire-control radar onto Japanese fighter jets.

Illuminating aircraft with radar signals a potential attack that could force targeted planes to take evasive measures, making it among the most threatening actions a military aircraft can take.

For its part, the Chinese embassy denied Tokyo’s claims, saying in a statement that “China solemnly demands that Japan stop smearing and slandering, strictly restrain its frontline actions, and prevent similar incidents from happening again”.

Beijing has summoned the Japanese ambassador, written to the United Nations, urged citizens to avoid travelling to Japan and renewed a ban on Japanese seafood imports, while cultural events involving Japanese performers and movies have also been hit.
