The incursion – the largest in a year – came after the US secretary of state, Antony Blinken, on Sunday warned China not to attempt to change the status quo around Taiwan, saying to do so would be a “serious mistake”. Democratic, self-ruled Taiwan lives under the constant threat of invasion by China, which has vowed to one day seize the island, by force if needed. On Friday the US state department said it would make it easier for US officials to meet Taiwanese representatives, defying pressure from China.
The sabre-rattling has increased since the 2016 election of Taiwan’s president, Tsai Ing-wen, who rejects the idea that the island is part of “one China”.
