The Chinese army encircled Taiwan from four directions on Saturday morning during the first day of a three-day military exercise, in apparent response to Taiwanese President Tsai Ing-wen's visit to the US.

Axar.az reports citing the state-run Global Times reported that according to the Chinese People's Liberation Army (PLA) Eastern Theater Command, they began the exercises by encircling Taiwan from four directions with combat alert patrols and joint exercises, which are scheduled to last until Saturday.

"This is a stern warning to ‘Taiwan independence’ secessionist forces and their collusion with external forces, and a necessary move to safeguard national sovereignty and territorial integrity," the daily said, citing a statement from PLA Eastern Theater Command spokesman Senior Colonel Shi Yi.

The latest development came after Tsai Ing-wen returned home on Friday from a 10-day trip to Central America and the US, where she met with US House Speaker Kevin McCarthy in California and received a global leadership award from a think tank in New York.

Earlier on Friday, China sanctioned two US institutions, including the Hudson Institute, which presented the Taiwanese leader with the award, and the Ronald Reagan Presidential Foundation and Institute, where she met with the US House speaker.
