InvestigationThe brutal return of conflicts between great powers shows the fragility of global production chains. Economic players are reconsidering their strategies and advocating decoupling that reduces interdependencies, particularly with China.
Originally defining in electronics the fact of separating two electrical circuits connected until now, the term “decoupling” has taken on geopolitical and economic meanings. According to the mood swings of the Atlantic Alliance, he designated the possibility of a lack of reaction from the United States to a Russian attack on Europe – for example during the Nixon or Trump presidencies – a fear which is no longer relevant at the time of the war in Ukraine. It also refers, in the reports of the Intergovernmental Panel on Climate Change (IPCC), to the hope of a separation between economic growth and growth in CO2 emissions.2. But today the word decoupling in English, and tuo gou in Chinese, refers to the tendency to reduce or even eliminate the ties of economic interdependence that unite the United States, and more broadly the West, to China: “A scenario in which the United States and China choose divergent technologies and trade standards, and rely on independent supply chains”explains Jeremy Ghez, professor of economics and international business at HEC, who coordinated a joint study on the subject by HEC, the American Chamber of Commerce and the law firm DLA Piper (“Economic Decoupling.

Hence the escalation, from spring 2018, of customs tariffs applied to Chinese imports, but also the ban on the sale of technological components to Chinese companies (such as ZTE, in April 2018), their exclusion from national markets “ strategic” such as telecommunications (Huawei, presidential decree of May 15, 2019), and even the New York listing, for lack of transparency on the accounts or because of the presence at their head of members of the Communist Party (“Holding Foreign Companies Accountable Act”, December 2020).
