As stated in the third Core Principle, managing investment policy
dynamically is of fundamental importance to ensure the continued
relevance and effectiveness of policy measures. Revisions in investment
policy may be driven by changes in strategy – itself caused by adaptations
in the overall development strategy – or by external factors and changing
circumstances. Countries require different investment policies at different
stages of development, policies may need to take into account those in
neighbouring countries, and be cognizant of trade patterns or evolving
relative shares of sectors and industry in the economy. Policy design and
implementation is a continuous process of fine-tuning and adaptation to
changing needs and circumstances.
