I am interested in the area of international economic law, as I want to pursue my career at international organizations like WTO or similar.

As I know, UCL and Georgetown are famous for this. But I don't know much in details. Can anyone please elaborate more or even name other universities you see it's famous in this regime.

Thank you :))

Honestly, international economic law, International trade law, WTO law, law and economics, and antitrust/competition law are all the same. Meaning, all you learn from these disciplines are a base-level understanding of "game theory". It would be imperative to investigate the module description of the course. Not to negate your plan but you would be wasting money and time.

Suggestion: consider taxation/tax law.

Kind regards.
