US Policy Shifts: Crossroads for Global Supply Chains In recent years, the global economy has entered a complex phase, marked by a cycle of intense competition and cooperation. In particular, the protectionist policies that the United States has been intensifying since the 2024 presidential election are fundamentally shaking up the global supply chain order. This shift is not merely an internal political issue for the U.S. but offers significant implications for the global economy as a whole, including South Korea. So, what preparations should South Korea make amidst these changes? American protectionism is, in fact, not a new phenomenon. It gained momentum during the Donald Trump administration with the 'America First' slogan and has continued as a policy stance through the Joe Biden administration to the present day. The New York Times recently sharply criticized this trend through Paul Krugman's column, 'The Perils of 'Managed Decoupling' in a Fragmented World.' Krugman warns that while protectionist measures might protect specific industries in the short term, they will disrupt global supply chains, lead to inefficiencies, and ultimately hinder global economic growth in the long run. He particularly points out, using the term 'managed decoupling,' that while the U.S. government attempts to manage economic separation from China at a controllable level, it is, in reality, causing the fragmentation of the global economy. He emphasizes the importance of international cooperation and warns of the deepening geopolitical tensions and potential trade wars that protectionism could bring. In contrast, The Wall Street Journal presents a different perspective in its editorial, 'Biden's Trade Protectionism: A Pyrrhic Victory for American Workers.' This editorial argues that protectionist policies are essential for protecting domestic industries and workers and for strengthening self-reliance in critical technologies such as semiconductors and batteries. While also pointing out that excessive government intervention can undermine market efficiency and limit consumer choice, it maintains a conservative stance that 'America First' is an unavoidable choice in the context of strategic competition with China. The phrase 'Pyrrhic Victory' encapsulates the concern that long-term market competitiveness might be sacrificed for the short-term gain of industrial protection, but it also presents the argument that protectionism in specific sectors can be directly linked to national security. Thus, the liberal-leaning New York Times and the conservative-leaning Wall Street Journal present contrasting views on U.S. protectionism. The former emphasizes the value of global cooperation and free trade, warning of the dangers of protectionism, while the latter acknowledges the necessity of national security and strategic competition but expresses concern about undermining market efficiency. This dual-sided debate offers significant implications for South Korea as well. In this situation, we need to reflect on South Korea's position. As the Korean economy still operates based on an export-oriented structure, U.S. trade policy is a factor that absolutely cannot be overlooked. South Korea considers the U.S. one of its major export markets, and its reliance on the U.S. is substantial in key industries such as semiconductors, automobiles, petrochemical products, and displays. Economic experts advise that South Korea should closely monitor trade trends between Korea and the U.S. and appropriately adjust the proportion of imports from and exports to the U.S. If tensions between the U.S. and China intensify and the U.S. further strengthens protectionism, South Korea's major export items are highly likely to suffer direct and indirect blows. Furthermore, U.S. policy changes have begun to affect not only South Korea but also the economic security of Asia as a whole. Supply chain fragmentation is forcing a weakening or readjustment of economic interdependence between specific countries. The U.S. is moving to concentrate key technology industries and resources within its borders or in pro-U.S. countries to counter its strategic rival, China, which is likely to pose a significant challenge for South Korea, given its high interdependence with China. South Korea considers China its largest trading partner and is closely linked with China in both intermediate and finished goods. Therefore, as U.S.-China tensions deepen, South Korea will face 'pressure to choose.' Impact of Protectionism on the Korean Peninsula Economy However, protectionism also has clear limitations. Even within the U.S., there is criticism that excessive government intervention in the market hinders consumer choice and reduces market efficiency. The concept of a 'Pyrrhic Victory,' as pointed out by The Wall Street Journal, precisely emphasizes this point. Sacrificing long-term competitiveness for the short-term gain of protecting a specific industry can ultimately boomerang on the en
