Taiwan sees biggest Chinese jet incursion after Blinken warning
The defence ministry scrambled aircraft to broadcast warnings to leave and monitored the planes as China's jets, including 18 fighters, entered the island's southwest Air Defence Identification Zone (ADIZ) for the tenth straight day this month.
The incursion -- the largest in a year -- came after 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 and 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.
Blinken's comments also followed the State Department's Friday announcement that it will make it easier for US officials to meet Taiwanese representatives, defying pressure from China amid high tensions.
The sabre-rattling has increased since the 2016 election of President Tsai Ing-wen -- who rejects the idea the island is part of "one China".
Some analysts and US military officials have warned tensions between Taiwan and China are now at their highest since the mid-1990s.
"What we've seen, and what is of real concern to us, is increasingly aggressive actions by the government in Beijing directed at Taiwan, raising tensions in the (Taiwan) Straits," Blinken told NBC's "Meet the Press".
He added: "All I can tell you is it would be a serious mistake for anyone to try to change the existing status quo".
Taiwan's ageing fighter fleet has suffered a string of fatal accidents in recent years as its air force is kept under constant pressure by China.
