Chinese jets fly sorties over Taiwan strait in show of force as US delegation departs

End of secretary of state Antony Blinken's three-day visit marks upsurge in military activity after period of relative calm

Taiwan has reported that a dozen Chinese warplanes flew sorties close to the island on Saturday, in a sudden surge of military activity just hours after the US secretary of state, Antony Blinken, left Beijing following talks with President Xi Jinping and top Chinese officials.

Before Blinken's three-day visit to China, US officials had pointed to a period of relative calm in the Taiwan strait over the past few months, after years of aggressive Chinese military manoeuvres and threats, as a factor in improving US-Chinese relations since Joe Biden held a summit meeting with Xi in November.
