BANGKOK (AP) — China has banned exports of key materials used for a wide range of products, including smartphones, electric vehicles, radar systems and CT scanners, swiping back at Washington after it expanded export controls to include dozens of Chinese companies that make equipment used to produce computer chips. Both sides say the controls are justified by national security concerns. Analysts say they could have a much wider impact on manufacturing in many industries and supply chains, depending on the ability of each side to compensate for loss of access to strategically important materials, equipment and components. Here’s why this could be a tipping point in trade conflict between the two biggest economies.
