A world index of open economies was released this week.
The index, first released in 2021, was compiled by the Institute of World Economics and Politics under the Chinese Academy of Social Sciences and the Research Center for the Hongqiao International Economic Forum. It was included in the World Openness Report 2022.
The 10 most open economies in 2020 were Singapore, Germany, China's Hong Kong Special Administrative Region, Ireland, Switzerland, the Netherlands, Canada, Malta, France, and the United Kingdom, according to the index.
It may be surprising to see the USA 23rd on the list. China is 39th.
On the other hand, you can consider the source, just like in many other instances.
