China launches security review of Palo Alto Networks products, escalating tech cold war

China has initiated a cybersecurity review of products from the US firm Palo Alto Networks, intensifying scrutiny of foreign technology amid rising tensions with the United States. This regulatory action deepens an existing standoff and serves as a powerful instrument that could restrict the company's ability to sell into critical sectors. The move highlights an escalating tech cold war, which may potentially reshape global cybersecurity alliances as China continues to tighten its security oversight.
