Japan has expressed its “regret” over a break-in at the Chinese embassy in Tokyo by a knife-wielding Japanese military officer, but China has said that response is “far from enough”.

China Seeks More Details

China’s foreign ministry said Japan has yet to provide full details of the incident.

“The Japanese side has expressed deep regret to the Chinese side regarding this incident, but this is far from sufficient,” said Lin Jian, spokesperson at the foreign ministry, during a regular news conference on Friday.

“We once again urge the Japanese side to conduct a thorough investigation as soon as possible and provide China with a responsible explanation.”

Japan Calls Incident ‘Regrettable’

Japan’s top government spokesperson, Minoru Kihara, described the incident, which took place on Tuesday, as “regrettable”.

He said the government would take steps to prevent such incidents from happening again.

The incident risks further straining Sino-Japanese relations.

Ties have already deteriorated since November, when Japan’s prime minister said the country could deploy its military if a Chinese move against Taiwan also threatened Japanese territory.
