A defence expert has warned that China’s live firing military drills and their infringement in Taiwanese waters “is an act of war” as Biejing has violated Taiwan’s “country’s territorial sovereignty.”

Arthur Zhin-Sheng Wang, a defence studies expert at Taiwan’s Central Police University, said that China has infringed three of the areas within Taiwanese waters, meaning the Chinese Navy are within 12 nautical miles of shore.

Wang said that by China using live fire in the country’s territorial airspace or waters is risky, he added, that “according to international rules of engagement, this can possibly be seen as an act of war.”

A spokesperson said at a briefing by Taiwan’s Defence Ministry, “Such an act equals to sealing off Taiwan by air and sea, such an act covers our country’s territory and territorial waters, and severely violates our country’s territorial sovereignty.”
