Shaping Thailand’s future
An industrial start with growing momentum through technology and sustainability
WHA Industrial Development is Thailand’s leading industrial developer, providing well-developed land, ready-built factories, and warehouses with total industrial solutions. Our comprehensive industrial utility solutions are designed to support efficient, sustainable and high-performance manufacturing operations.
For over 30 years, Thailand’s Eastern Seaboard has evolved into the nation’s premier industrial hub. In 2018, the Thai government introduced a 20-year strategy aimed at driving innovation and enhancing the country’s industrial competitiveness, with investment incentives. This transformation has been fueled by strategic investments in key comprehensive infrastructure projects within the Eastern Economic Corridor (EEC), which spans Chachoengsao, Chonburi and Rayong provinces.
Notable developments include the National Petrochemical Complex in Map Ta Phut, U-Tapao Airport and Eastern Aviation City in Rayong, the deep-sea container port at Laem Chabang in Chonburi, and the high-speed rail network to connect Thailand’s three major airports.

WHA’s industrial estates serve as strategic hubs for Thailand’s key industries, including automotive, electronics, electrical appliances, and consumer products. Our industrial estates form the nation’s most prominent automotive cluster, attracting significant investments from global industry leaders such as Ford, Mazda, Great Wall Motor, SAIC Motor (MG), BYD, CHANGAN, amongst over 450 world-renowned automobile manufacturers.
As a company, we have been at the forefront of transforming Thailand into a leading global industrial destination, providing world-class standard infrastructure, reliable utilities, and total industrial solutions that enable manufacturers to maximize operational efficiency. We continue to develop new investment destinations, such as WHA Eastern Seaboard Industrial Estate 5, and work with local authorities to establish new projects to bring many opportunities and benefits to surrounding communities.
Recognized as a premier destination for foreign direct investment, WHA Industrial Development continues to play a pivotal role in shaping Thailand’s industrial landscape, fostering growth, innovation, and long-term sustainable economic development.
