This is a false and dangerous argument that should be vigorously opposed. I have written the following paper on why this is so. I would be grateful if you could read this paper and consider what can be done. Do let me know any feedback you may have. Many OECD countries have submitted long reservation lists.
Many issues also remain unresolved.
Due to these difficulties, the OECD ministerial meeting in Paris at the end of April 1998 decided to suspend the negotiations for six months. Japan has also come out in favour of such a new Round. To boost this move, the EC has also claimed that at the WTO the developing countries can also participate, and this is thus more participatory. Proponents of an MAI in the WTO can also be expected to claim that labour and environmental issues will be taken care of, and also that suggestions to balance the rights and obligations of corporations can be considered. NGOs not be taken in by such an argument and should reject any move to get the WTO to negotiate an investment treaty.
