- National treatment, treatment no less favourable
Most investment agreements contain a national treatment obligation, which requires that a host State treat foreign-owned investments at least as well as similarly situated national investments, or foreign investors as well as domestic investors. This chapter first explores the historical development of the national treatment obligation. It then addresses national treatment in practice, with particular reference to the investment treaty practice of the last decade and a half. As part of that examination, it sets forth the difficult and unresolved issues in the national treatment jurisprudence, including the hurdles that claimants face in establishing a national treatment claim. Finally, it addresses some of the reservations to national treatment that States have included in their investment treaties.
