China has lodged a strong protest after a member of Japan's Self-Defense Forces on Tuesday allegedly broke into the Chinese embassy in Tokyo, raising grave concerns over rising neo-militarism. The intruder, identified by Tokyo police as a 23-year-old officer, reportedly threatened diplomats "in the name of God" with a knife later found near the scene. China's Foreign Ministry says the incident is egregious in both nature and impact, urging a thorough investigation and accountability. CGTN's Zhao Yunfei explains the growing concerns over Japan's rightward shift and its impact on bilateral ties.
