hard not to be a little neo-marxist

i've been contemplating recently how the only solution for developing countries should be opening their markets to foreign capital by which they also gain access to useful knowledge and technology. theoretically, it may fall into place; BUT for example, the European Partnership Agreements between less developed countries in Africa, The Carribean and The Pacific and the EU is impressive for how little no concern *the haves* grant to their dealing partners. in order to be able to send their products to the European markets, poor countries are required to make a compromise in their disadvantage and apply no taxation to the European products which will penetrate their markets. moreover, European countries make their consumers aware of what bringing products from far-away poor countries implies-carbon emissions-i.e. pollution.
to my mind (and please correct me if i'm wrong) african products don't stand a chance on EU markets, and soon they will be in the same situation at home, competing with subsidized, more qualitative European ones. doesn't EU sense how much the balance of this trade is tilting to its side? why widen the gap?
