"Meanwhile, Washington's nuclear policies, such as its AUKUS submarine cooperation with the UK and Australia, undermine the international nuclear non-proliferation system and significantly disrupt international and regional peace and stability, Zhang noted. He urged the US to engage in serious self-reflection and provide a responsible account to the international community. The spokesman also addressed the Taiwan question, warning that attempts to separate the island from mainland China will never be tolerated. “The Chinese people are determined to defend national sovereignty and territorial integrity,” he said, slamming Washington’s arms sales and military aid to Taipei as a violation of the one-China principle."
