The drills “solemnly warn external forces to stop interference and sternly warn... separatist forces to stop provocations,” Zhu Fenglian, a spokeswoman for China’s Taiwan Affairs Office, said on Wednesday.
She also stressed that China reserved the right to “take all measures” to protect its sovereignty, including the use of force.
Zhu’s remarks came after the administration of new US President Joe Biden expressed strong support for Taiwan.
On Saturday, Taiwan reported that China had sent multiple bombers, fighter jets, and anti-submarine aircraft to what Taipei called its air defense zone.
Later in the day, the US State Department said it was concerned by China’s “pattern of ongoing attempts to intimidate its neighbors, including Taiwan,” adding that Washington’s commitment to the self-ruled island was “rock-solid.”
