I am took online course on edX called Macroeconomic Management in Resource-Rich Countries in 2018. The first module of this course pointed me in the direction of an excellent website called The Atlas of Economic Complexity. It is maintained by the Center for International Development at Harvard University. Give it a look. As an example, it provides detailed information on the exports and imports of countries around the world.
See above for the links to the economic complexity atlas website as well as the edX website.
