What does the removal of the 'we do not support Taiwan independence' phrase from the US State Department's fact sheet mean and how has China reacted?

The removal of this key phrase signals a potential shift in US policy toward Taiwan, possibly indicating more openness to Taiwan's independence aspirations. China has reacted furiously, with its Foreign Ministry condemning the move as a violation of international law and a dangerous provocation that sends a wrong signal to Taiwan independence forces. Beijing views this as another example of the US using Taiwan to contain China and has urged the US to correct its mistakes immediately to avoid damaging Sino-US relations and stability in the Taiwan Strait.
