A 2024 paper says:
> China’s relevance as a manufacturing hub has risen from about 5% of global manufacturing production in 1995 to about 35% in 2020. Its production share was higher in 2022 than that of the next nine largest manufacturing countries in the world combined, including the US, Japan and Germany
> Jean et al. (2023) look at global dominance from another perspective. The authors identify product-level dominant positions in world trade, defined as a share of more than 50% of worldwide exports. Based on this measure, they find that out of a total of about 5,000 products, China held a dominant position in almost 600 products in 2019. This is outstanding and atypical when comparing this result to other countries and over time since 1970. For example, China holds a dominant position in at least six times as many products as the United States, Japan or any other country and twice as many products as the European Union considered as a whole
