Why Thailand Gets 14 Times More Tourists Than Sri Lanka

Sri Lanka reached a record 2.36 million tourist arrivals in 2025. Thailand received nearly 33 million. The gap is enormous, but the numbers hide a more complicated story about borders, airports, airline networks, short-haul travel, visas and how each country has built its tourism economy.

There is a question that comes up regularly in Sri Lanka’s tourism debate.

If Sri Lanka has beaches, wildlife, mountains, ancient cities, tea plantations, surfing, Ayurveda and a relatively small geographical area, why does Thailand receive so many more tourists?

The standard answer is usually some version of the same explanation: Thailand has better marketing, more hotels and a more developed tourism industry.

Those things matter.

But the numbers reveal something deeper.

Thailand’s advantage begins before a tourist books a hotel.

It begins with the way people can physically enter the country.

The headline number is almost 14 to one

Thailand recorded 32,974,320 international visitors in 2025, according to the Thai Ministry of Tourism and Sports. Sri Lanka recorded 2,362,521 tourist arrivals in the same year.

That makes Thailand’s international visitor count almost 14 times Sri Lanka’s.

But there is an important detail: Thailand’s 2025 total was actually 7.23 percent lower than the previous year. Sri Lanka’s total, meanwhile, increased by 15.1 percent.

So this is not a case of Thailand simply having a spectacular growth year while Sri Lanka was falling behind.

Sri Lanka was growing faster.

It was simply growing from a much smaller base.

But Thailand has something Sri Lanka physically cannot have

There is a major statistical difference between the two destinations that is often overlooked.

Thailand shares land borders with Myanmar, Laos, Cambodia and Malaysia.

Sri Lanka does not share a land border with another country.

That sounds obvious. Its effect on tourism numbers is not.

In 2025 Thailand recorded 4.52 million Malaysian tourist arrivals alone.

But the Thai government’s economic planning agency found that 78.04 percent of those Malaysian visitors entered Thailand through land border crossings.

That works out to roughly 3.53 million Malaysian arrivals entering overland.

This does not explain the entire difference. Thailand also receives enormous numbers of visitors from China, India, Russia, Europe, South Korea and the United States.

But it changes the way the 14-to-one comparison should be understood.

A weekend trip from Malaysia to Hat Yai or another southern Thai destination can count as an international tourist arrival.

A similar Malaysian traveller going to Sri Lanka must buy an international air ticket, pass through an airport and make a substantially larger travel commitment.

Thailand therefore has access to a category of high-frequency regional tourism that Sri Lanka’s geography does not permit.

Thailand’s tourism machine starts at multiple airports

The next difference is aviation.

Thailand does not depend on one airport to handle almost all of its international tourism.

Official Thai statistics for 2025 show international passenger traffic running through several major gateways, including Suvarnabhumi, Don Mueang, Phuket and Chiang Mai.

Suvarnabhumi alone handled more than 48.4 million international passenger movements in 2025, while Don Mueang recorded about 11.8 million and Phuket almost 9.9 million.

Sri Lanka’s situation is radically different.

The Sri Lanka Tourism Development Authority recorded 95.2 percent of all tourist arrivals entering through Bandaranaike International Airport in 2025.

Mattala handled only about 3 percent, while Jaffna International Airport handled around 0.5 percent.

This creates a tourism bottleneck.

A visitor travelling to the south, east, north or central highlands still overwhelmingly begins the trip at the same western gateway.

Thailand has a different model.

A tourist can fly directly into Bangkok, Phuket or Chiang Mai depending on the itinerary.

That changes the economics of travel.

A traveller interested primarily in Phuket does not have to fly to Bangkok first and then travel south. A traveller going to northern Thailand can arrive through Chiang Mai.

The airport becomes part of the destination strategy.

In Sri Lanka, the airport remains overwhelmingly a national gateway rather than a network of regional tourism gateways.

The route network tells the same story

IATA’s 2025 snapshot of Sri Lanka’s regional air connectivity found that the country had 82 scheduled routes, compared with 92 in 2015.

That represents an 11 percent decline over the decade.

The organisation also found that 94 percent of routes cancelled in 2025 carried fewer than 20,000 seats a year.

This is important because aviation connectivity is not simply about how many airlines appear on a list.

Airlines need enough passengers to make routes commercially viable.

If a route cannot generate sufficient year-round demand, it becomes vulnerable to cancellation.

Sri Lanka’s tourism industry is therefore caught in a feedback loop.

This is one reason Sri Lanka’s recent tourism weakness cannot be explained entirely by destination marketing.

Marketing can make somebody want to visit Sri Lanka.

It cannot create a flight that does not exist.

Thailand has turned its airline network into a tourism distribution system

Thailand’s tourism authorities have increasingly treated airlines as tourism partners rather than simply transport companies.

The Tourism Authority of Thailand’s 2025 strategy included an explicit “Airline Focus” approach involving airlines and tour operators to increase capacity and strengthen year-round connectivity.

The results can be seen in the long-haul market.

By December 2025, Thailand had received more than 10 million visitors from Europe, the Americas, the Middle East and Africa combined.

The UK alone passed one million visitors.

Thailand’s tourism authority reported that five airlines were operating direct UK-Thailand services during the 2025/26 winter season, providing about 11,100 seats a week.

That is not simply advertising.

It is a coordinated effort to make the destination physically easier to buy.

Sri Lanka is still heavily dependent on transit hubs

Sri Lanka’s own aviation data provides a revealing picture.

An SLTDA analysis of July 2025 found that Dubai, Doha and Abu Dhabi together accounted for more than one-third of tourist departure traffic.

Dubai alone represented about 14.5 percent, Doha 12.7 percent and Abu Dhabi 8.78 percent.

The Gulf hubs are enormously useful to Sri Lanka.

They also expose the country to a vulnerability that is easy to miss.

A European traveller may think they are booking a trip from London to Colombo.

Operationally, however, their journey may depend on a connection through another country.

When those hubs are disrupted, Sri Lanka can lose tourism demand without anything happening at Colombo airport itself.

That mechanism became visible during the Middle East air-route disruptions of 2026.

Lakbima has previously examined that dependence in detail in Sri Lanka’s tourism industry is feeling the Middle East air-route shock.

Then there is the visa question

Sri Lanka has also spent years debating whether entry should be made easier for tourists.

Thailand has used visa exemptions as a tourism instrument across major source markets.

Sri Lanka’s own free-visa policy only became substantially broader in May 2026, when the Department of Immigration began offering free 30-day tourist ETAs to nationals of 40 countries.

The list includes India, China, the United Kingdom, Australia, Germany, France, Japan, South Korea, Malaysia, Russia, the United States and Thailand.

The scheme still requires travellers to obtain an ETA before arrival.

This is a useful reform.

But it also illustrates the problem.

Thailand has spent years treating entry facilitation as part of its tourism infrastructure.

Sri Lanka has repeatedly treated it as a policy question to be debated and revised.

Thailand’s source markets are also built differently

Thailand’s 2025 visitor figures included 4.52 million Malaysians, 4.47 million Chinese, 2.49 million Indians, 1.90 million Russians and 1.56 million South Koreans.

Sri Lanka’s largest market was India, with 531,511 arrivals.

The UK was second with 212,277 and Russia third with 186,580.

China contributed about 132,000 visitors.

There is a major difference in the scale of the Asian markets available to the two countries.

Thailand sits directly beside some of the world’s largest populations and is embedded inside a dense Southeast Asian travel network.

Sri Lanka sits in the Indian Ocean.

That geographical advantage cannot be copied.

But the more interesting question is what Thailand has done with it.

Thailand did not depend on China alone

One of the more revealing developments in Thailand’s recent tourism numbers is that the country continued to attract huge volumes even while its Chinese market weakened.

Chinese arrivals fell by 33.55 percent in 2025 to 4.47 million.

Yet Thailand still recorded almost 33 million international visitors.

The country’s economic planning agency found that long-haul markets were becoming increasingly important to Thailand’s tourism revenue.

In the first quarter of 2025, long-haul visitors represented only about 37 percent of international arrivals but generated approximately 49 percent of inbound tourism receipts.

That is a significant distinction.

Thailand is not simply trying to fill hotels with the largest possible number of visitors.

It has been developing different markets for different economic purposes.

Short-haul visitors provide volume.

Long-haul visitors can provide longer stays and higher spending.

That combination gives the industry more than one source of demand.

Sri Lanka has a different problem: its visitors are concentrated

Sri Lanka’s 2025 tourism recovery was strongly driven by India and several European markets.

India alone supplied 531,511 visitors.

But Sri Lanka Tourism’s own analysis shows that the country remains heavily leisure-oriented.

In December 2025, 70.27 percent of arrivals were classified as pleasure or vacation travel.

MICE represented 8.06 percent and visiting friends and relatives 7.81 percent.

Business travel was only 1.3 percent.

Health and Ayurveda accounted for around 0.5 percent.

The country therefore has an unusually large dependence on the traditional holiday traveller.

That matters because holiday demand is more sensitive to airfare, weather, geopolitical disruptions and household budgets than some business and visiting-friends-and-relatives traffic.

There is another number Sri Lanka should worry about

The visitor count has recovered.

The nights have not fully recovered.

Sri Lanka’s average tourist stay was approximately 10.8 nights in 2018.

SLTDA’s 2025 figure was 8.29 nights.

That is roughly 23 percent fewer nights per visitor.

The significance is straightforward.

Two tourists arriving on the same day count as two arrivals whether they stay five nights or ten.

But hotels, restaurants, guides, transport companies, attractions and retailers do not experience those two tourists in the same way.

The industry earns money from time as well as people.

This is a point Lakbima has examined in Sri Lanka’s tourism paradox: more tourists, less time and money.

Thailand has its own tourism problem — and it is revealing

Thailand should not be presented as a perfect tourism model.

Its international arrivals fell in 2025.

Its Chinese market contracted sharply.

Its authorities are now talking about moving from “volume” to “value”.

The Bank of Thailand has also warned about flight cancellations, higher airfares and changing tourist behaviour.

Thailand is therefore dealing with many of the same pressures Sri Lanka faces.

The difference is the size and resilience of the underlying tourism system.

When one market weakens, Thailand has a much larger pool of other markets and much greater domestic travel demand.

Its 2025 domestic tourism volume was more than 200 million trips.

Sri Lanka has no equivalent domestic market.

That creates another structural difference.

Thailand can sell a holiday as several destinations

Thailand’s tourism system has another advantage that is less visible in national arrival statistics.

The country can sell multiple internationally recognisable destinations within one national trip.

Bangkok.

Phuket.

Krabi.

Chiang Mai.

Pattaya.

Koh Samui.

These destinations have their own international demand, accommodation markets, airports and tourism identities.

Sri Lanka has internationally recognised destinations too.

Colombo.

Kandy.

Ella.

Galle.

Yala.

Sigiriya.

Arugam Bay.

But the international aviation network does not treat them as independent gateways in the same way.

The overwhelming majority of tourists still enter through the western side of the country.

That means Sri Lanka’s tourism system has to move visitors after they arrive.

Thailand’s system can bring visitors closer to where they want to spend their holiday.

The room problem is more complicated than “Sri Lanka needs more hotels”

Sri Lanka had 59,578 registered rooms across 4,927 registered accommodation establishments in 2025.

But the distribution is highly uneven.

Western and Southern provinces together accounted for 36,155 registered rooms, or about 60.7 percent of the country’s registered room stock.

That concentration follows the existing tourism economy.

It also creates a problem.

If the country wants tourists to stay longer and spend more time in secondary destinations, those destinations need accommodation, transport, restaurants, attractions and trained workers capable of handling international demand.

A tourist cannot be marketed into an area that does not have enough viable tourism infrastructure.

The hidden issue is not just “marketing”

The evidence points to a different conclusion.

Sri Lanka does not have one tourism problem.

It has several connected ones.

So why does Thailand get more tourists?

The answer is not simply that Thailand has better beaches.

It is not simply that Thailand advertises more.

And the raw 33-million versus 2.36-million comparison is not entirely fair because Thailand benefits from millions of land-border entries that Sri Lanka can never generate.

The deeper answer is that Thailand has built a tourism system around access, scale and distribution.

It has neighbouring countries supplying short-haul traffic.

It has several international aviation gateways.

It has a large domestic market supporting hotels, airlines and attractions outside the international tourist season.

It has multiple internationally recognised destinations.

It has spent years working with airlines to create and sustain routes.

And it has enough visitor volume that airlines, hotels, tour operators and destinations reinforce one another.

What Sri Lanka could actually learn from Thailand

Copying Thailand is not realistic.

Sri Lanka does not have Thailand’s geography, population, land borders or domestic market.

But several lessons are transferable.

First, airports should be treated as tourism infrastructure, not merely aviation infrastructure.

Second, Sri Lanka needs to think about direct routes to destinations and source markets rather than simply counting airlines operating through Colombo.

Third, airline partnerships should be tied to measurable tourism outcomes: seats, routes, seasonal continuity, marketing and hotel demand.

Fourth, tourism policy should distinguish between volume markets and high-value long-haul markets.

Fifth, Sri Lanka needs more reasons for visitors to stay beyond the traditional seven- or eight-night circuit.

Sixth, the country needs tourism infrastructure outside the western and southern core if it wants to spread visitor spending geographically.

And finally, arrival numbers should no longer be treated as the only measure of success.

The number Sri Lanka should really be chasing

Sri Lanka’s official target for 2026 is at least three million arrivals.

That would be a substantial increase.

But another three million arrivals would not automatically solve the tourism industry’s structural problems.

If the average visitor continues to stay fewer nights than before, if most tourists continue to enter through one airport, if European travellers remain dependent on foreign transit hubs and if tourism spending remains concentrated in a few regions, the headline number can rise without transforming the industry’s underlying economics.

Thailand’s experience suggests something else.

The strength of a tourism industry is not just how many people arrive.

It is how easily they can arrive, how many places they can reach, how long they remain, how much they spend and how many businesses can participate in the resulting economy.

Sri Lanka has already demonstrated that it can recover its visitor numbers.

The harder question now is whether it can build the system around those visitors.

Editor’s note: International “tourist arrival” statistics are not perfectly identical across countries. Thailand’s figure includes land-border arrivals, while Sri Lanka’s tourism system is overwhelmingly air-dependent. The comparison is therefore used to examine the structural scale and mechanisms behind the difference, not to suggest that every Thai arrival represents the same travel pattern as a Sri Lankan arrival. Revenue figures also use each country’s official tourism methodology and should be treated as directional rather than as a perfect accounting comparison.
