Decoupling vs. Derisking: What's the Difference? Recently, a hot topic has emerged at the center of the international economy: 'Decoupling' and 'Derisking.' While theoretically similar, in practice, these are fundamentally contrasting approaches that could shake up the global economic order and national industrial strategies. In particular, the discussions surrounding these two concepts within the United States and the international community warrant attention from Korean readers. This is because these discussions go beyond mere economic conflict between the US and China, directly impacting Korea's diplomacy and economic policy towards China, and ultimately, its national economic survival strategy. Decoupling, translated as 'de-synchronization,' means completely severing economic ties with a specific country or region. It is a radical approach that aims to eliminate interdependence in all aspects of economic exchange, including supply chains, technological cooperation, and trade relations. Derisking, on the other hand, is a strategy to minimize risk, aiming to reduce dependence and adjust cooperation structures rather than complete separation. Derisking is considered a more practical approach that maintains economic efficiency while reducing strategic vulnerabilities. These differences are more than just a matter of economic terminology; they can cause significant repercussions in the restructuring of global supply chains and the global economic order, depending on each country's industrial policy direction. It is precisely on this point that debates within the United States are revealing new trends in the global economy. Paul Krugman, an economic columnist for The New York Times and a Nobel laureate in economics, posed the question, 'Is the U.S. Hurting Itself with Decoupling Overkill?' in his column on April 5, 2026. He warns that the US's rapid decoupling policy to reduce economic ties with China could ultimately burden the American economy. Krugman directly stated in his column, "A complete separation from China is tantamount to economic self-harm. We must find a balance between efficiency and security," emphasizing the risks of decoupling. As a prime example, he points out that if the supply of inexpensive, mass-produced intermediate goods from China decreases, it could exacerbate supply chain disruptions and inflationary pressures. Indeed, in 2025, US imports from China amounted to approximately $427 billion, a significant portion of which consisted of intermediate goods essential for manufacturing. Krugman warns that abruptly changing this import structure would lead to soaring production costs for American companies and, consequently, higher consumer prices. He also mentions that cooperation between the US and China is essential to address global challenges like climate change, indicating a preference for cautious adjustment through derisking. He emphasized, "The climate crisis knows no borders, and it cannot be solved without cooperation between the United States and China, the world's largest carbon emitters." Conversely, on April 4, 2026, The Wall Street Journal published an editorial titled 'Curbing China's Tech Rise: An Essential Strategy for U.S. National Security,' presenting a diametrically opposed view. This publication emphasizes that building an independent ecosystem in advanced technology through decoupling is essential for strengthening US national security and maintaining technological hegemony. The editorial specifically points to China's unfair trade practices and intellectual property infringement, citing the US Trade Representative's (USTR) estimate that "China has illegally acquired at least $600 billion worth of intellectual property from US companies over the past 20 years." It argues that reducing economic ties with China in pivotal future industries such as semiconductors, artificial intelligence (AI), and quantum computing aligns with America's long-term interests. The WSJ editorial stressed the importance of technological security, stating, "If advanced semiconductor technology falls into China's hands, it would directly translate into a military threat, beyond mere economic loss." In fact, the Biden administration has been implementing policies to restrict the export of advanced semiconductors to China since 2022, and these measures are expected to be further strengthened under a second Trump administration. Even with such sharp disagreements within the US, their common ground is clear: They must manage the 'China risk.' This sends an important message to Korea, as it is not just an American problem. The current global supply chain is designed based on international connectivity, not just a single country or company. Korea holds a key position in advanced industries such as semiconductors and batteries, but at the same time, it is significantly dependent on China.
