A free trade agreement (FTA) is usually a broader economic pact that may also include investment protections. The labels overlap: the agreement’s text, current legal status and dispute provisions—not its title alone—determine whether a particular investor has rights or a route to bring a claim.
What is the difference between a BIT and an FTA?
A BIT is generally designed around investment promotion and protection between two states. An FTA addresses a wider economic relationship and may include an investment chapter alongside trade, sustainable-development, facilitation or cooperation provisions. Some broader economic treaties contain obligations similar to those found in stand-alone BITs. UNCTAD’s International Investment Agreements Navigator distinguishes these forms while cataloguing agreements.

Neither label guarantees a standard package of rights. A BIT may differ substantially from another BIT, and an FTA’s investment chapter may be narrower or broader than a stand-alone treaty. The operative wording and the treaty’s status are decisive.

How do their investment protections compare?
Where an agreement provides investment protections, its clauses may address treatment of foreign investors and investments, protection against certain forms of state action, and transfers. The scope and limits depend on the specific text, definitions and exceptions.
#1 Best Overall
| Issue | What to examine | Why it matters |
|---|---|---|
| National treatment and most-favoured-nation (MFN) treatment | How the treaty defines comparable investors or investments, and any listed exceptions | These concepts concern non-discrimination, but the wording and qualifications determine their reach. The U.S. Department of Commerce describes them in its explanation of U.S. BIT provisions; that explanation is illustrative, not a universal template. Source. |
| Minimum standard of treatment, fair and equitable treatment (FET), and full protection and security | The treaty’s exact standard, definitions, cross-references and limits | Similar terms can have different legal content depending on their context. The U.S. explainer describes how these concepts appear in U.S. treaty materials, not what every treaty requires. |
| Expropriation and compensation | Covered measures, the treaty’s expropriation test, compensation terms and exclusions | A clause’s existence does not establish that a particular government measure is covered or unlawful. |
| Transfers | Which payments or funds may be transferred, and any exceptions or conditions | Transfer provisions may be qualified; check the actual clause rather than assuming unrestricted movement of funds. |
| Admission and establishment | Whether obligations apply to establishing an investment, or only after it exists | Post-establishment protection does not by itself establish a right to enter a market or make a particular investment. |
| Exceptions and regulatory space | Any tax, health, environmental, security, prudential or public-welfare carve-outs, as drafted | Exceptions can narrow obligations or claims. Their effect is treaty-specific. |
Does an FTA protect foreign investors?
It can, if it contains applicable investment provisions. Those may sit in an investment chapter or elsewhere in the agreement. OECD’s assessment of selected FTAs treats investment alongside trade, sustainable development and other topics, including facilitation-related provisions. That broader context can matter when interpreting the agreement as a whole; it does not mean every FTA provides the same investor rights. OECD, Investment in Free Trade Agreements.
Can an investor sue a government under a BIT or FTA?
Not automatically. Investor–State dispute settlement (ISDS) exists only where the applicable treaty provides a route for it, and the investor and claim must meet the treaty’s conditions. Some agreements omit ISDS. UNCTAD reported in a 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. UNCTAD, International Investment Agreements Issues Note.
Rank #2
Where ISDS is included, check who may bring a claim, which obligations and claims are covered, and what procedural steps apply. Notice and consultation periods, waiting or local-remedy requirements, the forum, transparency rules and any review mechanism can affect whether and how a case proceeds. A dispute clause is not a general right to sue a government over any adverse action.

How should an investor identify the treaty that may apply?
- Identify the relevant states. Determine the investor’s nationality and the country where the investment is located, then search for a BIT, an FTA with investment provisions or another potentially applicable agreement between them.
- Confirm the agreement’s status. Check whether it was signed and entered into force, and whether it has been amended, terminated or is subject to a survival clause. A treaty listed historically or signed by both states may not govern a new investment. UNCTAD’s Navigator classifies agreements and links to treaty examples; verify the current record and read the treaty itself.
- Test investor and investment coverage. Read the definitions for nationality, ownership or control, eligible assets and temporal scope. A company’s place of incorporation, ownership structure or the timing and nature of an asset may affect whether the definitions are met.
- Map the substantive obligations and exceptions. Check the relevant protections, any admission or establishment rules, and the exceptions that could qualify them.
- Read the dispute provisions separately. Establish whether ISDS is available, whether the investor can invoke it for the relevant claim, and what preconditions, deadlines, forum and procedural rules apply.
For an actual investment or dispute, the treaty text must be considered alongside domestic law, the facts and qualified legal advice. This comparison is general information, not legal advice.

What recent treaty trends say—and do not say
UNCTAD’s published counts illustrate that treaty forms and protections are changing, but the figures cover different periods and denominators and should not be combined into one measure.
