In practice, economic politics between one country and another are not the same, depending on their economic system. Although different in the application of economic politics, but the same goal is to create prosperity of the people.
In the 21st century it's almost all about economic politics. Though a bit of ego and hypocrisy works. But citizens are so concerned about their own well being that every government is forced to prioritize the economic well being (as well inter-national economic race) than any other global issues.
