UNCTAD's Work Programme on International Investment Agreements (IIAs) actively assists policymakers, government officials and other IIA stakeholders to reform IIAs with a view to making them more conducive to sustainable development and inclusive growth.
International investment rulemaking is taking place at the bilateral, regional, interregional and multilateral levels. It requires policymakers, negotiators, civil society and other stakeholders to be well informed about foreign direct investment, international investment agreements (IIAs) and their impact on sustainable development.
Main goals of UNCTAD’s Work Programme on IIAs
• Reform the international investment agreements (IIAs) regime to enhance its sustainable development dimension,
• Provide comprehensive analysis on key issues arising from the complexity of the international investment regime,
• Develop a wide range of tools to support the formulation of more balanced international investment policies.
The three pillars of activities
• Research and policy analysis: monitoring trends, identifying key emerging issues and providing cutting-edge knowledge on IIAs from a sustainable development perspective,
• Technical assistance: delivering trainings, seminars and workshops; conducting IIA and model BIT reviews; offering ad-hoc advice to strengthen the capacity of beneficiaries in handling the complexities of the IIA regime,
• Intergovernmental consensus-building: exchanging and sharing best practices and experience with the view to fostering global investment governance.

IIA Navigator
This database of IIAs – the IIA Navigator – is maintained by UNCTAD’s IIA Section. You can browse through IIAs concluded by a particular country or country grouping, view recently concluded IIAs, or use the Advanced Treaty Search for sophisticated searches tailored to your needs.

IIA Mapping Project
The IIA Mapping Project is a collaborative initiative between UNCTAD and universities worldwide to map the content of IIAs. The resulting database serves as a tool to understand trends in IIA drafting, assess the prevalence of different policy approaches and identify treaty examples.
The “Mapping of IIA Content” allows browsing through the project results to date (the page is regularly updated as the new results come in).

Project Description & Methodology document
International investment agreements (IIAs) are divided into two types:
(1) bilateral investment treaties and (2) treaties with investment provisions.
A bilateral investment treaty (BIT) is an agreement between two countries regarding promotion and protection of investments made by investors from respective countries in each other’s territory. The great majority of IIAs are BITs.
The category of treaties with investment provisions (TIPs) brings together various types of investment treaties that are not BITs. Three main types of TIPs can be distinguished:
1. broad economic treaties that include obligations commonly found in BITs (e.g. a free trade agreement with an investment chapter);
2. treaties with limited investment-related provisions (e.g. only those concerning establishment of investments or free transfer of investment-related funds); and
3. treaties that only contain “framework” clauses such as the ones on cooperation in the area of investment and/or for a mandate for future negotiations on investment issues.
In addition to IIAs, there also exists an open-ended category of investment-related instruments (IRIs). It encompasses various binding and not-binding instruments and includes, for example, model agreements and draft instruments, multilateral conventions on dispute settlement and arbitration rules, documents adopted by international organisations, and others.
Key concepts
- The mapping structure, displayed in the “Select mapped treaty elements” tab, is a “table of contents” that includes all of the mapped treaty elements. It corresponds to the typical structure of an IIA.
- The mapped treaty elements are elements of an investment treaty mapped in the course of the IIA Mapping Project. The number of mapped treaty elements exceeds 100. Each mapped treaty element has a set of pre-defined mapping options to choose from.
- The mapping options indicate the approach taken in the treaty to the relevant mapped treaty element. Mapping options can be of the “Yes/No” type or they can indicate the treaty approach more specifically (e.g. the type of fair and equitable treatment clause (FET) – qualified / unqualified / none etc.). Each mapped treaty element includes the “Inconclusive” and “Not applicable” options.

The IIA Navigator is continuously adjusted as a result of verification with, and comments from, UN Member States. It is primarily built on information provided by governments on a voluntary basis. A treaty is included in a country's IIA count once it is formally concluded; treaties whose negotiations have been concluded, but which have not been signed, are not counted. A treaty is excluded from the IIA count once its termination becomes effective, regardless of whether it continues to have legal effect for certain investments during its “survival” (“sunset”) period.
While every effort is made to ensure the accuracy and completeness of its content, UNCTAD assumes no responsibility for eventual errors or omissions in these data. The information and texts included in the database serve a purely informative purpose and have no official or legal status. In the event of doubt regarding the content of the database, it is suggested that you contact the relevant government department of the State(s) concerned. Users are kindly asked to report agreements, errors or omissions by using the online contact form.
The IIA Mapping Project is a collaborative initiative between UNCTAD and universities worldwide to map the content of IIAs. Individual treaties are mapped by law students from participating universities, under the supervision of their professors and with the overall guidance and coordination of UNCTAD.
The mapping results included in the IIA Mapping Project database serve a purely informative purpose. The mapping of treaty provisions is not exhaustive, has no official or legal status, does not affect the rights and obligations of the contracting parties and is not intended to provide any authoritative or official legal interpretation.
While every effort has been made to ensure accuracy, UNCTAD assumes no responsibility for eventual errors or omissions in the mapping data. In the event of doubt regarding the correctness of mapping results, users are kindly asked to contact us via the online contact form.
