The Chinese Foreign Ministry has strongly criticized a new $571 million US military aid package to Taiwan approved by outgoing President Joe Biden, stating it violates the ‘One China’ principle. China warns it will take ‘all necessary measures’ to protect its national sovereignty and territorial integrity, marking Taiwan as a ‘red line’ in US-China relations. Washington has long been Taiwan’s primary supplier of military equipment and protector, which Beijing considers a significant provocation, viewing Taiwan as a Chinese province.
