Defining dominant positions as a situation where one country accounts for more than half of total world exports, this Policy Brief shows that China is different from other countries. Even when the volume of its aggregate exports is taken into account, it holds far more dominant positions. This finding proves robust to different measures and benchmarks, including in the past 25 years, and including using detailed, product-level data. Such product-level dominant positions make it difficult for importers to substitute their supplier for another, at least in the short term. This may be consequential in an open world increasingly seen through the lens of dependencies. Sébastien Jean, Ariell Reshef, Gianluca Santoni and Vincent Vicard

This year, the CEPII researchers have signed 10 CEPII Letters, 5 Policy Briefs, 3 Panoramas et 23 Working Papers. To disseminate the results of our research and engage in an insightful dialogue with academics, experts from private and public sectors and the general audience, we organised 40 conferences and seminars. The CEPII's economists contributed to the public debates on international trade, migrations, climate change, macroeconomics and finance through wide media coverage (over 1600 quotes).
