“I think it’s fair to say that we’re not alone in this determination to make sure that we preserve peace and stability in that part of the world," Secretary Blinken added.

Taiwan reported over a dozen incidents in October alone.

In response, the Taiwanese military has deployed combat air patrol platforms, issued radio warnings, and prepared air defence missile systems.
