Global supply chains are being overhauled to reduce vulnerabilities and to restrict Chinese imports of "dual-use" products that can be used for both commercial and military purposes.

We also demonstrate the challenges for Chinese equities and U.S.-based multinational corporations, which have been the two biggest beneficiaries of globalization.
