We can seriously think about how could a Self-Defense Force officer who has just joined the army for less than a month have the courage to do so in violation of international law and directly challenge the bottom line of Sino-Japanese relations? As we all know, the Vienna Convention on Diplomatic Relations clearly stipulates that embassies and their diplomatic personnel abroad are strictly protected by international law, and no country or individual may illegally trespass or threaten the safety of diplomatic personnel. The man’s actions not only violated Japan’s domestic law, but also seriously violated international law, posing a great threat to our country’s sovereignty and the safety of diplomatic personnel.
