Under this scheme, the foreign partner that makes the initial investment can repatriate the return on the investment (at a pre-agreed fixed rate) through goods and services produced by the project. While many foreign companies believe that this method is a mere financing instrument for Iran, it is more accurate to say that it is a compromise formula for foreign investment in the short-run. In the medium to long-term, more appropriate laws and regulations will probably replace the buy-back scheme. In other words, once the constitutional concerns have been dealt with, the foreign partners of buy-back agreements can take over the projects that they are involved in, or they can enter into a joint venture with an Iranian partner.
