ABSTRACT
The first attempts to develop regional and multilateral rules concerning foreign investment date back to the Havana Charter of 1947. From the end of the 1940s, various instruments were devised that reflected the priorities of the time. Chronologically, the period extending from the 1950s to 1970s was especially preoccupied with controlling foreign investments. Developing countries sought to retain their national sovereignty, and foreign investors sought to protect their investments against political risks and the nationalisation of their assets. In this respect, Decision 24, adopted by the Andean Pact, symbolized these concerns.
