Thailand’s Tourism Industry Warns of “Defining Nexus” as Vietnam Outpaces Growth and Infrastructure Gaps Widen

Thailand’s tourism leaders have issued a blunt warning: the kingdom is at a strategic crossroads as it faces slowing arrivals, infrastructure bottlenecks and intensifying competition from Vietnam and other regional destinations. At the Thailand Tourism Forum 2026 in Bangkok, industry executives said the country must overhaul its tourism strategy or risk ceding ground in a sector that has long been one of its main economic engines.​

C9 Hotelworks managing director Bill Barnett told delegates that international arrivals to Thailand fell 7.2 percent in 2025, even as Vietnam posted a 20.4 percent increase in foreign visitors over the same period. Vietnam’s gains, he argued, reflect aggressive investment in airports, coastal infrastructure and marketing, as well as a reputation for value and new experiences. Thailand, by contrast, is struggling with airport congestion, ageing resorts in some destinations and policy uncertainty around visas and taxation.​

Forum participants highlighted several structural challenges:

At the same time, neighbouring destinations are stepping up. Vietnam’s Da Nang, Nha Trang and Phu Quoc have added new international routes, branded hotels and entertainment options, while Indonesia pushes Bali‑plus‑one itineraries and the Philippines gears up to host ASEAN’s 2026 tourism agenda in Cebu and Bohol. Gulf travellers, once almost defaulting to Thailand for beach and medical tourism, now have more options across Dubai, Ras Al Khaimah, Oman’s Musandam and Salalah, and Saudi’s Red Sea projects, intensifying the fight for high‑spend segments.

Thai hoteliers and developers at the forum called for a shift from volume to value, echoing regional trends in Jordan and the Philippines. They urged policymakers to prioritise infrastructure upgrades, route development deals, sustainable‑tourism standards and incentives for product refreshes, especially in mid‑scale and upper‑midscale segments that cater to Asian families and regional business travellers.​

There is also a call for closer integration with digital platforms and data‑driven marketing, as younger travellers rely on social media, creator content and dynamic pricing rather than traditional tours. Thailand must, executives say, move faster on e‑visa simplification, digital payments interoperability and smart‑destination tools that manage visitor flows and protect sensitive sites.

For investors from the Gulf, Japan, Korea and Singapore, the message is nuanced. Thailand remains a large, diversified tourism market with deep supply chains and strong brand recognition, but it is no longer the only or necessarily the fastest‑growing bet in ASEAN hospitality. Vietnam’s momentum, combined with emerging opportunities in the Philippines, Indonesia and even Cambodia and Laos, argues for a more portfolio‑based approach to regional tourism exposure.

Thai policymakers have signalled awareness of the stakes. The Tourism Authority and related ministries have floated plans for airport expansions, secondary‑city development, medical‑and‑wellness corridors and sustainability‑linked incentives, but execution will be critical. The 2026 forum’s tone suggests that industry is prepared to support a pivot—provided the government can deliver predictable, pro‑investment policies.​

In short, Thailand’s tourism “defining nexus” is as much about regional competition and shifting traveller preferences as it is about domestic infrastructure. How Bangkok responds over the next three to five years will determine whether the kingdom remains a cornerstone of Asian tourism portfolios—or becomes one strong player among many in an increasingly crowded field.
