The charity Medicins sans Frontieres (MSF) says that hidden clauses in the free trade agreeement (FTA) currently being negotiated between Europe and India will prevent the manufacture and distribution of crucial generic medicines produced in the country.
"There are dirty legal tricks being used," says Dr. Tido von Schoenangerer, who runs the MSF campaign for essential medicines. "Any person living with HIV in the developing world is facing a future scenario in which the medicines they need will be under threat."
Meanwhile the World Health Organisation, the UN's public health body, has echoed MSF's concerns, saying that if the trade deal does indeed include clauses governing the production of cheap generic medicines, the ramifications for the public health could be serious.
The issue hinges on a so-called "data exclusivity" provision in the free trade agreement, which campaigners say would effectively copyright information gathered in the clinical trials that prove the effectiveness and safety of medicines.
