Ask most analysts why the Bimstec FTA has gone nowhere since 2004, and you get one answer: Politics. Big powers can't agree, small states feel pushed around, and even after eight rounds of negotiation, the agreement remains far from finalizing their agreements.
But this article makes a sharper claim. Even if every Bimstec leader signed the agreement tomorrow, trade would barely move. The deeper problem isn't political will. It's the sheer unevenness of customs systems, product standards, and border infrastructure across the region. This is a regulatory problem, not a diplomatic one, and it needs a different fix.
The conventional account has real evidence behind it. The framework agreement was signed in 2004, but two decades later, its six parts, covering goods, services, investment, customs, trade facilitation, and dispute settlement, remain unfinished.
Bimstec's own Secretary-General has called the FTA's progress "very slow," and said member states are now considering finalizing only the parts closest to agreement instead of waiting for the whole package.
But this explanation has a problem. It can't explain why trade stays low even in product categories where tariffs are already fairly low, and even between countries with decent relations.
If politics were the whole story, trade should flow more easily where diplomacy is warmest. That isn't what happens. Something else is keeping goods stuck at the border.
It also can't explain why other regional blocs with their own share of political tension, such as Asean, still manage to trade far more with each other.
Where the real wall stands
Look past the negotiating table and toward the customs shed, and the picture becomes clearer. The trade numbers are damning on their own.
Intra-Bimstec trade stood at 6.7% of members' total trade in 2023, translating into regional trade worth $53.49 billion, up from $46 billion in 2019. For a bloc that includes India, one of the world's largest economies, this is strikingly small.
The region's own data shows why. The Asian Development Bank's 2022 trade facilitation framework grades each country's customs systems against WTO standards. Thailand and India report 91.6% and 72.3% full compliance, with no procedures stuck in the weakest category. Myanmar, by contrast, has only 5.5% full compliance, with 85.3% still in the weakest category. Nepal fares similarly poorly, at just 2.1% full compliance.
This isn't a picture of political disagreement. It's a picture of infrastructure and staffing running at completely different speeds across the same trade bloc.
This unevenness costs real time and money at the border. A monitoring study of one Bangladesh trade corridor found that completing routine trade procedures took roughly half a month for an experienced trader, and 18 days for a new trader. Border crossing alone took over six hours for imports.
On a single 455-kilometre corridor, cargo trucks spent close to 30 hours in transit, over 11 of which were pure waiting time. These delays are not just an inconvenience for traders. They add directly to the final price of goods, which makes Bimstec-made products less competitive even inside their own region
And the type of barrier matters most. Sanitary and technical standards, rules on food safety, product testing, and certification, they all add up. These aren't simple paperwork checks. Smaller exporters struggle to meet them because compliance needs functioning testing labs, which many border regions simply don't have. When a country lacks a certified lab near its crossing point, an otherwise reasonable safety rule turns into an impassable barrier.
Put together, these threads tell a clear story. Bimstec's economies aren't only failing to agree on paper, they're also failing to converge in practice also.
Thailand's digitized customs system has almost nothing in common with Bhutan's land-port capacity. A signature cannot paper over that gap. It has to be built into the agreement itself, through shared testing facilities, mutual recognition of standards, and real technical assistance for the countries furthest behind.
Bimstec's own strategy documents admit this is still missing, noting that without mutual recognition agreements, exporters face costly duplicate testing every time a product crosses a new border.
Why this distinction matters for policy
This isn't just an argument over labels. It changes where Bimstec should spend its effort. If the problem were mainly political, the fix would be more summits and leader-level trust-building. But if the deeper problem is regulatory unevenness, summits are the wrong tool.
What's actually needed is slower, less visible technical work such as joint investment in border testing labs, mutual recognition agreements, harmonized paperwork, and dedicated funding for Myanmar, Nepal, and Bhutan, which remain decades behind on digitized border systems.
There's reason to think this shift is already happening inside the bloc. Officials have floated splitting the FTA into components and finalizing the parts closest to completion instead of waiting for the whole agreement at once. That is, in effect, an admission that the technical layer, not the political layer, is where real progress can happen fastest.
Bimstec's stalled FTA is usually told as a story about mistrust between governments. That story isn't false, but it's incomplete.
The data points to a different diagnosis: The region's real wall is regulatory, built from mismatched testing labs, uneven digitization, and standards nobody has agreed to recognize across borders.
Political summits will not fix this. Only steady, long-term work on fixing these rules and systems will. Until Bimstec makes that a top priority, its free trade agreement can’t boost trade alone.
