When preparing to set up factories in Southeast Asia, the first truly difficult question to answer is often not "which city to go to," but rather "which country to go to." Vietnam, Thailand, and Malaysia are all major options for Taiwanese manufacturing companies, but the industrial ecosystems of these three countries differ significantly, and choosing the wrong direction can have substantial consequences. Once land leases, policy relationships, and talent structures are established, relocation and adjustments are difficult to make in the short term.

This article compares the core differences between industrial zones in the three countries from four key dimensions of site selection, helping manufacturers establish a clear judgment framework during the preparation phase.

Four key dimensions of site selection decision

There is no single optimal solution for industrial park location, but there are four dimensions that manufacturers often regret not having considered carefully: cost structure, policy incentives, logistical conditions, and compliance complexity. The permutations and combinations of these four dimensions across the three countries largely determine which type of manufacturing industry is best suited for which location.

Cost structure refers to long-term expenditures such as land, electricity, and wages. Policy incentives include tax breaks, import/export facilitation, and restrictions on foreign ownership. Logistics conditions include port throughput, cross-border transportation timeliness, and cost. Compliance complexity depends on the predictability of customs, tax, and labor regulations, as well as the administrative efficiency of local governments.

Vietnam: Clear cost advantage, but compliance preparation is essential.

Vietnam is currently the top choice for Taiwanese businesses to set up factories, with its core advantages lying in relatively low labor costs and land rents, coupled with tariff advantages for exports to Europe provided by multilateral trade agreements such as the CPTPP and EVFTA. Northern Vietnam, mainly Hanoi and Haiphong, is concentrated in the electronics and machinery industries; Southern Vietnam, mainly Ho Chi Minh City, Binh Duong, and Dong Nai, boasts a mature manufacturing supply chain.

Regarding import and export regulations, EPE (Export Processing Enterprise) status allows for tax-free imports of raw materials, making it a common factory setup structure for the manufacturing industry. However, bonded supervision will tighten after 2026, and the requirements for accounting management and customs coordination will increase. It is recommended to incorporate compliance setup into the pre-construction phase, even before site selection.

The main challenges lie in the high frequency of regulatory changes, significant regional disparities in local government administrative efficiency, and a limited supply of mid- to high-level local talent. It is recommended to conduct on-site verification of the customs service quality and power supply stability of the target industrial zone before selecting a site.

Thailand: With the most complete policy system, it is suitable for long-term investment.

Thailand's biggest advantage lies in policy predictability. The BOI (Thailand Board of Investment) offers systematic tax exemptions and preferential treatment for foreign ownership; the EEC (Eastern Economic Corridor) provides additional incentives for high-value-added manufacturing industries such as electronics, automobiles, and aviation. Industrial zones boast well-developed infrastructure, and its power supply stability is the highest among the three countries.

In terms of logistics, Laem Chabang Port is a major transshipment hub in Southeast Asia, with efficient sea freight connections to Europe and the Middle East. The completion of the China-Thailand railway will also improve the timeliness of land connections to Yunnan, China, making it suitable for manufacturing industries that require supply chain collaboration between China and Thailand.

The main challenge lies in the higher wage levels compared to Vietnam, and the fact that land acquisition costs in some industrial zones are nearly double those in Vietnam, requiring direct confirmation of current quotes from the industrial zones. For labor-intensive manufacturing sectors seeking purely low-cost operations, Thailand's advantages are relatively limited; however, for businesses requiring policy stability and planning for long-term development, Thailand is the preferred choice.

Malaysia: The combined advantages of an English-speaking environment and high-value-added manufacturing

In recent years, the US-China trade friction has attracted a large amount of production capacity to relocate to Malaysia, resulting in a high concentration of semiconductor, electronics, and medical device manufacturing industries. Its core advantages are threefold: English is the business language, significantly reducing communication costs; there is an ample supply of mid-to-high-level talent, making it easier to integrate foreign managers locally; and the MIDA (Malaysian Investment Development Authority) has relatively high efficiency in approving foreign investment incentives for the manufacturing sector.

Industrial zones are mainly located in Penang (with a complete semiconductor supply chain), Selangor (around Kuala Lumpur, diversified manufacturing), and Johor (connected to Singapore's logistics hub). Johor Bahru, due to its proximity to Singapore, has lower warehousing and factory costs than Singapore, and can also access Singapore's financial and legal services, making it a popular location for high value-added manufacturing.

The main challenge lies in the higher overall costs compared to Vietnam, making labor-intensive manufacturing a less desirable option. It is suitable for manufacturing sectors with high talent requirements, proximity to high-quality supply chains, or a need for an English-speaking environment.

Quick Comparison of Core Differences in the Three Kingdoms

A quick comparison across four dimensions: Vietnam has the lowest cost structure; Thailand is second, with moderate barriers to entry for manufacturing; Malaysia has the highest overall cost, but its electricity and land costs in some industrial zones are competitive, and employer social security burdens are lower than in Thailand; Thailand has the most systematic BOI system in terms of policy incentives, Malaysia's MIDA has high approval efficiency, and Vietnam's EPE offers clear import and export incentives; Laem Chabang Port in Thailand and Port Klang in Malaysia have the most advantageous logistics conditions, while ports in northern Vietnam are still expanding; Malaysia has the lowest compliance complexity, Thailand is in the middle, and Vietnam has the highest frequency of regulatory changes.

The starting point for site selection decisions should not be "which country is best," but rather "which country's conditions best match my manufacturing type, talent needs, export markets, and cost budget." Each of the three countries has its own suitable manufacturing profile, and making this comparison during the preparation phase is far less costly than adjusting after entering the market.
