The economic activities of Indian business groups in Thailand have a long history. If we examine the establishment of representative Indian business groups in Thailand chronologically, the Diwanchand Group comes first, followed by the GP Group, Indorama Group, Adithya Birla Group, and Tata Group. Shivnath Rai Bajaj, who leads the Diwanchand Kundanlal Group, and Kirt Shah, who leads the GP Group, are PIO (Persons of Indian Origin). On the other hand, A. P. Lohia, who leads the Indorama Group, and S. S. Mahansaria and Deepak Mittal, who head the Adithya Birla Group, are NRIs (Non-Resident Indians). However, there is “a continuity” among these industrial groups, and the borders between PIO and NRIs are not closed. The inroads into Thailand made by the Tata Group symbolize the phenomenon of the “Rising New India.” Today, the central location of the Indian business groups in Bangkok is no longer Samphen-Pahurat (Little India) or the Ban-Kaek area; it is Sukhumvit. The Thai-Bharat Cultural Lodge, an association with a long history, has become fairly desolate today. This locational change of the main business activities of Indians in Bangkok is the most remarkable phenomenon that differs from the situation in the 1980s.
