A bilateral investment treaty (BIT) is generally a focused agreement between two countries to promote and protect investments by each country’s investors in the other. A free trade agreement (FTA) is broader and may include investment protections in a dedicated chapter. The categories overlap: the agreement’s title alone does not tell an investor what rights apply. The text, legal status, and the investor’s circumstances do.
What is the difference between a BIT and an FTA?
A BIT is centered on investment between two states. UNCTAD defines it as an agreement concerning the promotion and protection of investments made by investors from each country in the other’s territory. See the UNCTAD International Investment Agreements Navigator for treaty classifications and examples.

An FTA typically addresses a wider economic relationship. It may cover trade and other policy areas as well as investment, including through an investment chapter. UNCTAD distinguishes stand-alone BITs from broader economic treaties that include BIT-like obligations; the OECD likewise assesses selected FTA chapters as covering investment alongside trade, sustainable development, and other topics, including facilitation-related provisions. See the OECD overview of investment provisions in free trade agreements.
These are general patterns, not a universal rulebook. Some FTAs provide investment protections, some do not, and BITs also differ in their wording and coverage. To identify an investor’s rights, examine the particular agreement and whether it applies to that investor and investment.

Which protections might an agreement provide?
Common investment-protection concepts include non-discrimination and minimum standards of treatment. A U.S. Department of Commerce explainer describes national treatment, most-favoured-nation (MFN) treatment, and a minimum standard that references fair and equitable treatment (FET) and full protection and security. These are examples from U.S. treaty materials, not a template for every treaty. The specific text, definitions, and exceptions determine what each obligation means in a given agreement. See the U.S. Department of Commerce explanation of bilateral investment treaties.
- National treatment concerns how a covered foreign investor or investment is treated relative to domestic investors or investments, subject to the treaty’s terms.
- MFN treatment concerns treatment compared with investors or investments from other countries. Its operation depends on the agreement’s wording and qualifications.
- Minimum standard, FET, and full protection and security refer to treaty standards whose scope must be determined from the particular text and its legal context.
- Other possible provisions include rules on transfers and expropriation, but their presence, definitions, and limits vary by treaty.
Similar labels can conceal important differences. An obligation may be qualified, limited to particular stages of investment, or subject to exceptions. Do not infer a remedy or outcome from a clause name alone.
Rank #2
Does an FTA protect an investor before an investment is made?
Not necessarily. Agreements differ on whether they protect market access or establishment—such as entry into a market—or whether protections attach only after an investment exists. A general investment-protection clause is not, by itself, proof of a right to enter or establish a business. Check the agreement’s admission and establishment provisions, the definitions of investor and investment, and any reservations or exceptions.
Can an investor sue a government under a treaty?
Only if the applicable agreement provides a route for that investor to bring the relevant claim and the procedural conditions are met. Investor–State dispute settlement (ISDS) is not automatic and is not present in every treaty. UNCTAD reported in its 2026 note that 43 per cent of treaties concluded in the five years preceding the note lacked ISDS provisions. That figure describes recent treaty conclusions, not the share of all treaties currently in force. See the UNCTAD 2026 IIA Issues Note.
Rank #3
Where ISDS exists, the agreement determines which claims may be brought, who has standing, and what steps must happen first. Relevant details can include notice and consultation periods, waiting or local-remedy requirements, the forum, transparency rules, and review procedures. A treaty may protect an investment without giving the investor a direct treaty-based arbitration claim.
How should investors compare the applicable agreements?
Start with the treaty pair—both states—and the agreement’s current legal status. Then test the investor, asset, protections, and dispute provisions against the text rather than relying on the instrument’s label.
Rank #4
- Identify the instrument and parties. Determine whether the relevant document is a BIT, an FTA with an investment chapter, or another treaty with investment provisions, and confirm which states are parties.
- Verify status and dates. Check signature, entry into force, amendments, termination, and any survival clause. A treaty that was signed or appears in a historical list may not govern a new or existing investment today. Use the treaty text and an up-to-date official record, such as the UNCTAD Navigator.
- Test investor and investment coverage. Read definitions of investor and investment, including nationality, ownership or control, covered asset types, and temporal scope. The investor and asset must meet the particular agreement’s requirements.
- Map the substantive protections. Locate the actual terms for national treatment, MFN, minimum standard or FET, full protection and security, transfers, and expropriation, where included. Read qualifications alongside each obligation.
- Check the investment stage. Establish whether the rules cover admission or establishment, post-establishment operations, or both.
- Read exceptions and carve-outs. Look for provisions addressing areas such as tax, health, environment, security, prudential regulation, and public welfare, and determine how they are drafted to operate.
- Trace the dispute path. Confirm whether ISDS is available, what claims it covers, who may bring them, and which notice, consultation, waiting, local-remedy, forum, transparency, or review rules apply.
- Account for the wider agreement. In an FTA, consider how investment provisions sit alongside trade, sustainable-development, facilitation, and cooperation commitments.
For a particular investment or dispute, the treaty text is only one part of the analysis; domestic law, the facts, and qualified legal advice also matter.

UNCTAD’s figures describe different periods and denominators, so they should not be combined into one rate or treated as a measure of all treaties currently in force.

- UNCTAD reported that at least 17 BITs and 13 broader treaties with investment provisions were concluded in 2024 in its 2025 World Investment Report chapter. See the World Investment Report 2025.
- UNCTAD’s 2024 report overview said traditional BITs accounted for fewer than half of new treaties, reflecting a shift toward broader economic agreements with investment provisions.
- UNCTAD also reported in 2024 that about half of global FDI stock remained covered by unreformed international investment agreements (IIAs), and connected that legacy exposure with a higher risk of ISDS cases. This is UNCTAD’s framing of the reported stock, not a prediction about any specific investment or dispute.
These snapshots help explain why treaty design and status deserve attention, but they cannot establish which agreement protects a particular investor.
