I want to know the answer to the following question:
When did Estonia unite with the WTO?
All the background I'm provided with is that "With assistance from the European Union, the World Bank and the Nordic Investment Bank, Estonia completed most of its preparations for European Union membership by the end of 2002 and now has one of the strongest economies of the new member states of the European Union.[citation needed]". Is that enough to answer the question?
Answer: no
