Taiwan lives under the constant threat of invasion by China, which sees the self-ruled, democratic island as part of its territory to eventually be reclaimed, by force if necessary.
The final quarter of 2021 saw a massive spike of incursions from China into Taiwan's air defense identification zone (ADIZ), with the biggest single day coming on October 4, when 56 Chinese warplanes entered the zone.
The island's defense ministry said late Sunday it saw 39 warplanes from China enter Taiwan's ADIZ - the second-largest number of incursions on record, which is shared with October 2 last year.
