Chinese diplomats injured one of their Taiwanese counterparts during a scuffle in Fiji earlier this month, a senior Taiwanese official said, highlighting rising concerns over Beijing’s aggressive tactics as part of their "wolf warrior” diplomacy.

Two uninvited diplomats from the Chinese Embassy in Fiji were asked to leave an event celebrating Taiwan’s national day in Suva on Oct. 8 after they were seen photographing other guests, Taiwan’s Deputy Foreign Minister Harry Tseng told lawmakers in Taipei on Monday.

When confronted by Taiwanese officials, the Chinese diplomats initiated a physical confrontation, leaving one staff member from the Taiwanese representative office in Fiji needing hospital treatment for a head injury, Tseng said.
