Thailand Seeks Hong Kong Capital for 24 Square Kilometre EEC Smart City

A New Urban Hub Meets Hong Kong's Financial Markets

Thailand is seeking financing through Hong Kong for a planned smart city covering 24 square kilometres inside its Eastern Economic Corridor (EEC). The proposal would connect the financial centre's investors and financing expertise with a new urban hub intended to support advanced manufacturing, technology businesses and high quality urban living.

Chula Sukmanop, secretary general of the Eastern Economic Corridor Office, outlined the ambition at the 10th Belt and Road Summit in Hong Kong. Hong Kong investors have already committed about US$2 billion to EEC projects since 2018, making the city one of the corridor's leading foreign sources of capital, behind China, Japan and Singapore.

The smart city remains at the conceptual stage as of September 13, 2025. The EEC Office is consulting the Hong Kong Trade Development Council on tender structures that could attract international bidders and financing over many years. A tender is a process in which companies compete for a contract by submitting proposals and prices.

The EEC stretches across Rayong, Chonburi and Chachoengsao, three provinces east of Bangkok. Launched in 2017, it is a central part of Thailand 4.0, the country's strategy to develop more advanced industries. Major seaports, industrial estates and growing electric vehicle supply chains already give the proposed city a surrounding business base.

Thailand's proposal brings together two needs: capital to build a city and services that help businesses and workers function once it opens. Roads and factories alone will not deliver the intended urban experience. Reliable utilities, transport, digital services and places to live are also part of the plan.

Why Thailand Wants Hong Kong's Help

Hong Kong offers Thailand access to a large pool of money available for investment, legal and advisory expertise, and institutional investors familiar with Asian infrastructure. These investors manage substantial funds and can consider projects that take years to build and repay their financing.

Chula presented Hong Kong's international funding reach as a reason to seek support there. A complex city project may need both equity, meaning investment in exchange for ownership, and debt, meaning borrowed money that must be repaid.

Thailand could use different financing channels at different stages. Budget allocations and development partners might support work before construction. Bank loans could fund early utilities, while project bonds could become an option after completed assets generate dependable income. Refinancing through Hong Kong when conditions are favourable could reduce costs across the project's life.

Hong Kong's existing investment in the EEC gives the proposal a relationship to build upon. The roughly US$2 billion committed since 2018 covers corridor projects, while the new city would require its own financing arrangements.

What the Smart City Would Contain

The proposed city would sit within a corridor that already brings together ports, industrial estates and the U Tapao aviation area. Officials describe a setting where businesses can establish operations quickly, recruit skilled workers and connect to international supply chains.

Streamlined regulations and digital government services are part of that concept. A coordinated master plan would connect energy, water, transport and data systems, supporting advanced manufacturers, research laboratories and service companies.

Designs are not final. Possible features include smart mobility, engineering that can withstand climate pressures, fast digital connectivity, district energy and cooling networks, rooftop solar where feasible, automated waste and water systems, and fibre networks capable of supporting services at the scale required for 5G.

District cooling supplies cooling to several buildings through a shared network. Urban logistics hubs and shared mobility fleets could help reduce congestion, while a digital twin, a detailed virtual model of the city, could let planners test traffic signals, power use and land layouts before changing the physical city.

How Contracts Could Turn Plans Into Services

Thai planners are likely to divide the development into multiple tenders covering utilities, transit, data platforms and property. Dividing the work would spread risk among investors and operators, while allowing the state to set performance standards for each service.

International firms could partner with Thai companies, creating opportunities for technology transfer, training and local hiring. The practical test would be whether services remain reliable and affordable for the people and businesses using them.

The EEC Office's consultation with the Hong Kong Trade Development Council includes market sounding, a process of asking potential investors and contractors what they would need to participate. That work can help shape contracts, broaden competition and improve pricing.

Competitive tenders tend to separate land development from essential services and specify measurable standards for power, water, transit and digital platforms. Those standards give public authorities a way to assess whether an operator is delivering what it promised.

Construction could also proceed in stages. Initial work might concentrate on main roads, power lines and water plants. Later phases could add districts combining homes, businesses and services, university or institute campuses, and areas dedicated to health technology, automotive electronics and other target sectors. Early tenants could help pay for later works, reducing dependence on public money.

The Financing Options Under Discussion

Hong Kong's financial market offers several possible routes. Project finance banks can arrange syndicated loans, in which several lenders share the financing of utilities or transport lines. Asset managers can buy project bonds, through which investors lend money to a project.

Private equity and infrastructure funds could take ownership stakes in companies operating power, water and transit systems. Real estate investment trusts could hold completed commercial properties, allowing developers to receive money from assets they have built.

Green bonds and sustainability linked bonds are also potential options. Green bonds finance eligible environmental projects, while sustainability linked bonds connect financing terms to specified targets. District energy, efficient buildings and transport producing less carbon could support such financing. Hong Kong has arrangers, rating agencies and verifiers that help prepare and assess these instruments for international buyers.

Investor interest in reducing emissions and improving resilience to climate pressures makes the city's eventual design relevant to its financing. The selection of buildings, utilities and transport systems would affect both daily operations and the kinds of funding it could seek.

Hong Kong Financial Secretary Paul Chan has said the city expects to return to an operating account surplus in the 2025 to 2026 fiscal year, helped by active equity trading and new listings. An operating account surplus means revenue exceeds operating spending. Chan connected stock market turnover with government stamp duty revenue:

Paul Chan, Hong Kong's financial secretary, said that for every HK$100 billion of transactions, about HK$130 million in stamp duty is expected.

Thailand's attraction to Hong Kong rests on having several funding routes available over time. Different investors and lenders could support different stages, from preparing land and utilities to financing completed assets with established income.

Chula's Case for Belt and Road Cooperation

The Belt and Road Initiative, the programme backed by China, remains part of a debate about debt, transparency and benefits for local communities. Chula's position at the summit was that a country's own decisions determine how useful the programme becomes.

Chula, the EEC Office secretary general, described the initiative in terms of how governments choose to apply it:

Chula Sukmanop, secretary general of the Eastern Economic Corridor Office, said the Belt and Road Initiative is a tool, and its effectiveness depends on how a country uses it.

Thai officials argue that Thailand has been selective, concentrating on projects that bring technology and jobs. Their approach stresses screening projects, designing contracts carefully, controlling costs and setting clear standards for environmental and social impact assessments.

Chinese companies have been particularly active in the corridor's electric vehicle and energy projects. Thai authorities point to employment gains as factories move from testing production lines to mass production. They also see future benefits from rail and airport improvements that could support cargo movements, tourism and aerospace services.

Electric Vehicle Factories Give the City an Industrial Base

Chinese investors received approvals for projects worth about US$8.4 billion in the wider corridor cluster between 2019 and 2024. Electric vehicle manufacturing was a leading theme. BYD is among the companies building factories intended to serve Southeast Asia and other export markets.

Chula said electric vehicle factories in the corridor now employ around 7,000 Thai workers. The industry has created thousands of local jobs as assembly lines move from reliance on talent brought from overseas towards Thai teams.

Training programmes with vocational schools and universities aim to expand that workforce. Battery assembly, power electronics, robotics and quality control are among the skills being developed. The planned smart city is expected to accommodate suppliers and research partners that could help companies develop products faster and increase the value created locally.

Locating related businesses close together can make production more efficient. Chip makers, battery specialists, software teams and logistics companies can solve problems faster and move components over shorter distances. The corridor's seaports and expressways already offer manufacturers a time advantage. Serviced land, data centres and flexible laboratory space could strengthen those connections.

The corridor's development and related exchanges span several years:

• 2017: Thailand launched the EEC as part of its Thailand 4.0 strategy.
• Since 2018: Hong Kong investors have committed about US$2 billion to corridor projects.
• 2019 to 2024: Chinese investors received project approvals worth about US$8.4 billion in the wider corridor cluster.
• 2023: The Hong Kong Smart Living Pavilion showcased urban technology solutions in Bangkok.
• September 13, 2025: The smart city remains at the conceptual stage, with financing and tender structures being explored.

Trade Rules Shape the Investment Pitch

Thailand's appeal as a manufacturing location also brings a trade policy challenge. Companies from China and elsewhere are considering production in Thailand to serve the United States and other markets, making rules of origin central to their plans.

Rules of origin determine where a product is considered to have been made. They can examine the share of local content and the processing carried out in a country. A factory importing most components and doing only limited assembly may fail to meet the requirements for preferential tariffs.

Thai officials have signalled that they intend to manage production rules so Thailand does not become a route for avoiding tariffs. This requires tracking local content and supply chains, alongside testing products against stricter thresholds being considered in some markets.

Some of those thresholds are in the range of 60 to 80 percent content, compared with the common 40 percent baseline used in many trade agreements. The higher thresholds would require a greater qualifying share of a product's value or content under the applicable rules.

Thailand has also used financing to cushion businesses when tariffs rise or demand changes. The Government Savings Bank has previously provided soft loans, lending on more favourable terms, to companies under pressure from tariff changes. Such support gives small and medium businesses working capital while they adjust sourcing and production.

Technology Exchanges and Bangkok's Traffic Pilot

Thailand and Hong Kong already have contacts around smart urban technology. The Smart City Consortium organised the Hong Kong Smart Living Pavilion in Bangkok in 2023, with support from the Hong Kong Trade and Industry Department. Such exchanges can connect companies that may later form groups to bid for contracts.

Bangkok also offers a practical example of the services a smart city could use. The city administration partnered with Google on a programme using large amounts of data and artificial intelligence to adjust traffic signals during peak hours. Its aim is to shorten queues and reduce air pollution from vehicles idling in traffic.

Residents can report traffic trouble spots through the Traffy Fondue platform, giving engineers feedback as problems occur. Combining information from residents with data from transport systems and sensors can help authorities identify where changes are needed.

The EEC city could adopt and expand approaches like these. A shared data platform could help planners decide where to add a bus lane, extend the time a signal stays green or move freight journeys outside busy periods. These operational changes could make daily travel shorter and improve air quality.

Land, Costs and Public Services Will Test Delivery

The planned city faces constraints beyond attracting investors. Transparent plans and steady execution will be necessary to secure both capital and the people needed to make the development work.

Land assembly and zoning require clear ownership documents and fair compensation before work starts. Cost control requires limiting the expansion of project scope and using contract terms that account for changes in material and labour prices. Financing dominated by loans with short repayment periods would expose the project to repeated refinancing pressure.

Environmental safeguards would need to meet Thai and international standards covering air, water and habitats. Community support would depend partly on reliable services and affordable housing that allows workers to live near their jobs. Cybersecurity would be needed to protect data and the technology operating energy, water and transit systems. Open technical standards could reduce dependence on a single supplier and allow providers to change as technology develops.

Public consultation and environmental studies can reduce conflict. Contracts linking payment to performance can encourage operators to meet service targets, while independent monitors can track delivery and publish results. A varied investor base can reduce exposure to a financing shock. Combining Hong Kong channels with domestic banks and regional partners could strengthen that approach.

The next steps centre on how Thailand packages the contracts and selects its partners. No tender opening or construction date has been given. Those decisions will shape the city's cost, pace and quality, including whether the proposed urban services become dependable parts of everyday life.
