The US-China trade war continued for over three years since 2018, with sanctions and retaliatory tariffs imposed by both sides covering a wide range of product categories. Although the US and China reached a First Phase Trade Deal in 2020, most tariffs have remained in place under the new Biden Administration after it took office in January 2021. There is also no sign of deescalation on US-China technology rivalry. In this context, this paper first explores the development and impact of the trade war from a New Trade Theory perspective, focusing on China's "Strategic Trade Policy" and the US's retaliation. This paper concludes that the outlook of the trade war under the new Biden Administration is not positive, as most of the issues that have risen in light of China's pursuance of its "Strategic Trade Policy" remain unresolved. Second, this paper discusses the implications relating to trade and investment structures and the subsequent supply chain re-configuration development, and offers some possible hedging strategies for Taiwan's businesses.
