That accusation has been made by the US after China sent 93 military planes into Taiwan’s air defence zone in 5 incursions since Friday. Taiwan’s Premier Su Tseng-chang said “China has been wantonly engaged in military aggression, damaging regional peace”. And the US says the incursions are “destabilising, risks miscalculations and undermines regional peace and stability.” China is yet to comment, but it has previously said the flights are to protect its sovereignty over Taiwan and to discourage “collusion” between Taiwan and the US. It stems from China seeing Taiwan as a breakaway province that it wants to claim, whereas Taiwan sees itself as a sovereign state. President Joe Biden has said the US would intervene if China invaded Taiwan, but officials have talked that down.
