Hua Chunying, a Chinese Foreign Ministry spokeswoman, has expressed serious concern over the US Navy sending two warships through the Taiwan Strait on Monday.
Taiwan's Defense Ministry, for its part, said in a statement that they were aware of the "routine" operation and that the Taiwanese army "has the ability to maintain the security of the seas and the airspace to ensure regional peace and stability."

Pentagon spokesman Colonel Rob Manning, in turn, confirmed that "in the Taiwan Strait, earlier today, the USS [guided-missile destroyer] Curtis Wilbur and USS [guided-missile cruiser] Antietam conducted a routine Taiwan Strait transit in accordance with international law."
He described the transit as "the US commitment to a free and open Indo-Pacific," pledging that "the US Navy will continue to fly, sail and operate anywhere international law permits.

Manning also referred to the US maintaining "coordination and contact with the appropriate nations, authorities and parties" when conducting the transit, saying that it was "certainly not the Department [of Defense]'s intention to raise tensions or any kind of escalation" across the Taiwan Strait.
The US, along with many other countries, does not recognize Taiwan as a sovereign nation and officially adheres to the "One China" policy. However, Washington has maintained informal relations with the de facto government of Taiwan despite breaking diplomatic ties with Taipei in 1979.
