All countries have something to trade. Many of the world’s poorest countries have a lot of natural resources so they can take part in trade. Even if a country does not have sufficient natural resources it still has people. In order to be able to take part in the globalized manufacturing industry it need only be willing to accept lower wages than its rivals. Alternatively if it is landlocked and has not opportunity to trade in manufactures it can invest in education in order to become a services hub. All states have a comparative advantage somewhere, they just need to find it.
