The US disgraced Taiwan and Taiwan welcomed it.

I didn't know that the Taiwan Strait in Taiwan's territory was an international sea area whereby vessels were free to navigate without permission.

The US vessels sailed through the Taiwan Strait in Taiwan's territory while China naval vessels followed the US in China's territory.  What the US did was telling the world that Taiwan's territory was an international water in which any vessel could perform freedom of navigation without permission.

I couldn't believe that Taiwan would welcome the US's FON in its territory.  What a joke!
