How investment treaty arbitration works for Bangladesh-related disputes
When a government measure damages a foreign investment, the investor's contract may not be the only source of protection. Investment treaty arbitration allows qualifying investors to bring claims directly against a State under a bilateral investment treaty or similar instrument, for breaches such as expropriation without compensation, unfair and inequitable treatment, discrimination or restrictions on transfers of funds. We advise investors and State-linked parties on disputes involving Bangladesh, and Bangladeshi investors with assets abroad. This work sits within our dispute resolution practice in Bangladesh, alongside our commercial arbitration team. Investment treaty arbitration is one tool among several.
Bangladesh has signed bilateral investment treaties with a range of countries, including the UK, the US, Germany, Japan and China, and has been a party to the ICSID Convention since 1980. For investment treaty arbitration, each treaty is different. The definitions of investor and investment, the substantive protections, the conditions for bringing a claim and the available forums all vary, and some treaties have been amended, replaced or terminated. Every analysis therefore starts with the authentic text of the relevant treaty and its current status, rather than general assumptions about what investment treaties usually provide in practice.
Bangladesh has experience of investment treaty arbitration as a respondent. In the well-known Saipem case under the ICSID Convention, a tribunal found that interference by Bangladeshi courts with an ICC arbitration breached the Italy-Bangladesh treaty. Disputes in energy and natural resources have also been arbitrated internationally against Bangladeshi State entities. These cases show that claims can arise from court actions, regulatory changes and contract disputes with State-owned companies. They also show why investors and government bodies both benefit from early, careful legal analysis before positions harden and a dispute becomes public, with consequences for future investment.
Barrister Tahmidur Rahman and Barrister Remura Meheruba Mahbub lead our investment treaty arbitration work, drawing on their practice in international arbitration, foreign investment and project finance. Adv Syed Wahid, our founding partner, advises on related court proceedings in Bangladesh, including writ petitions that may run in parallel with a treaty claim. We work with counsel in the UK, US, UAE, China, India and Singapore and with international arbitration specialists, often acting as Bangladesh counsel within a wider international team. The Legal 500 Asia Pacific ranks Tahmidur Remura Wahid (TRW) Law Firm for dispute resolution in Bangladesh.
Investment treaty arbitration is usually a last resort. Most investors want to keep operating, and governments want to maintain investor confidence. The Invest Bangladesh Act 2026 merged BIDA, BEZA and the PPP Authority into Invest Bangladesh, which has operated since 23 August 2026, and engagement with the relevant authority, ministry or regulator can sometimes resolve a problem before a formal notice is needed. Treaties also commonly require a period of amicable negotiation. We advise on using that period well, and on how to preserve the claim while talks continue.

Treaty jurisdiction and claim assessment
Before any investment treaty arbitration, we assess whether a treaty applies by reviewing the investor's nationality and ownership chain, the nature and timing of the investment, the State measure in issue and any jurisdictional conditions. We also consider denial of benefits clauses, legality requirements and whether a contractual forum clause affects the claim, and give a frank view of the strengths, weaknesses and cost before any formal step is taken.
Notices and amicable settlement periods
Most treaties require written notice of the dispute and a cooling-off period before arbitration can begin, and some require recourse to local courts for a time. We draft notices that preserve the claim and set out the treaty breaches clearly, and plan negotiations with the government during that period, keeping a careful record so that procedural conditions are demonstrably met if the dispute proceeds to investment treaty arbitration.
ICSID and UNCITRAL proceedings
We act as Bangladesh counsel or co-counsel in investment treaty arbitration under the ICSID Convention, the ICSID Additional Facility or the UNCITRAL Rules, often administered by the Permanent Court of Arbitration. Our work includes evidence from Bangladeshi witnesses and records, expert evidence on Bangladeshi law, analysis of regulatory history, and preparing memorials and hearing materials alongside international counsel and damages experts, and preparing Bangladeshi witnesses for cross-examination.
Defence of State-linked parties
We advise government bodies and State-owned enterprises on responding to notices of dispute, managing parallel contractual arbitrations and court cases, and coordinating evidence across ministries and agencies. Early legal input can narrow the dispute, identify jurisdictional objections and support informed decisions on settlement. We work with the government's chosen international counsel where a formal defence of the treaty claim is required, and on parallel commercial negotiations with the investor.
Parallel proceedings and contract claims
Investment treaty arbitration often runs alongside commercial arbitration, writ petitions or civil suits in Bangladesh. We map how each process affects the others, including fork-in-the-road and waiver clauses, the risk of double recovery and the effect of local court decisions on the treaty case. The aim is a coordinated strategy in which each step strengthens, rather than undermines, the investor's overall position throughout the dispute and any settlement.
Award enforcement and recovery
ICSID awards are binding and subject only to the Convention's annulment procedure, and contracting States must enforce the pecuniary obligations as if they were final local judgments. Non-ICSID awards are enforced under the New York Convention. Execution against State assets still raises questions of sovereign immunity. We advise on recovery strategy, including identifying commercial assets and negotiating structured settlements with the State and its agencies, where that offers faster recovery.

Meet the firm →01What is the difference between investment treaty arbitration and commercial arbitration?
Commercial arbitration is based on an arbitration agreement in a contract, usually between companies, and resolves disputes about that contract. Investment treaty arbitration is based on a State's standing offer to arbitrate in a treaty, which a qualifying foreign investor accepts by starting proceedings. The claim is against the State itself, and it concerns breaches of international law standards, such as fair and equitable treatment or protection against expropriation, rather than breach of contract. The two can overlap where a State entity is also the contract counterparty, and the interaction needs careful analysis before either claim is started.
02Which Bangladesh measures can lead to investment treaty arbitration?
Claims can arise from many types of State conduct, including cancellation or non-renewal of licences, regulatory changes that destroy the value of an investment, discriminatory treatment, failure to pay amounts owed by State entities in some circumstances, restrictions on repatriating funds, outright or creeping expropriation, and court decisions that deny justice. The measure must usually be attributable to the State under international law. Ordinary commercial disagreements with a State-owned company may not be enough on their own. We review the measure, the investor's treatment over time and the treaty wording to assess whether a credible and worthwhile claim exists.
03Our investment is held through a Singapore or Dutch holding company. Can we still bring a treaty claim?
Possibly. Many investors hold investments through intermediate companies, and a claim may be available under the treaty between Bangladesh and the State of that company, if one exists and is in force, subject to the treaty's definition of investor. Some treaties include denial of benefits clauses that exclude shell companies without substantial business activities. Tribunals also scrutinise restructurings made after a dispute was foreseeable, and may treat them as an abuse of process. We review the ownership chain, the dates and the substance of each entity to determine which treaties are realistically available for an investment treaty arbitration claim.
04How long does investment treaty arbitration take, and what does it cost?
These cases are typically lengthy and expensive. From notice to award, proceedings often take several years, with additional time for annulment or set-aside applications and enforcement. Costs include tribunal and institutional fees, counsel, damages and industry experts, and translation of documents. Tribunals may order the losing party to pay costs, but outcomes vary. Third-party funding is used in some treaty cases and raises its own disclosure and control issues. We help clients assess whether the likely recovery justifies the investment of time and money, and how to keep costs proportionate throughout the proceedings and any enforcement stage.
05Do we need to go to the Bangladesh courts first before starting a treaty claim?
It depends on the treaty. Some treaties require a period of local litigation before international arbitration, while others allow a claim after a negotiation period only. Some contain fork-in-the-road clauses, under which choosing local courts for the same dispute may bar a later investment treaty arbitration. Starting a writ petition or civil suit in Dhaka without considering these clauses can therefore be risky. We assess the specific treaty text before any court step is taken, and advise on whether urgent local relief can be sought without compromising the international claim or the investor's broader relationship with government.
06Can investment treaty arbitration be used by Bangladeshi investors abroad?
Yes, if Bangladesh has a treaty in force with the host State and the investor and investment fall within its terms. Bangladeshi businesses increasingly invest in other countries, and outbound investment requires approvals under Bangladeshi foreign exchange rules, which also affect how the investment is structured and documented. An investment treaty arbitration against another State follows the same principles: notice, cooling-off, jurisdiction and merits. We advise Bangladeshi investors on treaty protection when they invest and on claims if a host State takes adverse measures, working with counsel in that State on local remedies and evidence.
07Will a treaty claim end our business and relationships in Bangladesh?
Not necessarily, but it can strain relations with government, regulators and State-owned counterparties, and it often becomes public. Many investors use the notice and negotiation period to reach a commercial solution, and some cases settle after proceedings begin. A claim can also be suspended while talks continue. The decision whether to proceed should weigh the value of the claim against the investor's continuing operations, reputation and future plans. We help investors communicate firmly, clearly and constructively with the relevant authorities, so that the legal position is protected while the door to settlement remains open at every stage.
08How are investment treaty arbitration awards enforced against a State?
ICSID awards must be recognised by all ICSID contracting States as binding, and their pecuniary obligations enforced as if they were final local judgments, subject to the annulment procedure. Non-ICSID awards are enforced under the New York Convention in the courts of the country where assets are found. In both cases, State assets used for public or sovereign purposes, such as diplomatic or central bank property, are often immune from execution. Recovery therefore depends on identifying commercial assets, or on negotiation. Many States settle or pay awards without contested enforcement, but planning for enforcement remains important from the outset.
From first call to resolution.
- 01
Treaty and measure review
We review the investment, ownership chain, State measure and applicable treaties, identify jurisdictional conditions and time limits, and give an initial view on the strength and value of a potential claim, including likely costs, timing and the evidence needed.
- 02
Notice and negotiation
We prepare and serve the notice of dispute, engage with Invest Bangladesh, ministries or other authorities during the cooling-off period, and preserve the claim while exploring settlement options with the government before any investment treaty arbitration begins.
- 03
Arbitration proceedings
If the dispute continues, we work with international counsel to commence and run the investment treaty arbitration, gathering Bangladeshi evidence, witnesses and legal opinions and supporting each phase through to the final hearing and post-hearing submissions.
- 04
Award and recovery
After an investment treaty arbitration award, we advise on annulment or set-aside proceedings, recognition and enforcement, sovereign immunity issues and negotiated payment arrangements, aiming for practical recovery rather than a paper result that cannot be collected.
