If you click the countries tab, you’ll find a table with countries, and the number of cases as a respondent state vs cases that corporations in their state have taken out against foreign states.
If you put it in excel, and sort by largest number of cases as a claimant state, you’ll find that the US, the Netherlands, and the UK as the biggest exploiting countries. (Which actually explains how the Netherlands got so rich, their tendency for nationalism, and why the bourge was pushing so hard for brexit)
Sort by most cases as a dependent state and you’ll find that Argentina, Venezuela, Mexico and Egypt as the countries that are the most exploited.
Some countries like Spain and Russia are both exploiting and exploited. China has surprisingly few cases despite the breadth of its operations.
