The move came following requests made to late Chief Minister J Jayalalithaa by two US-based Tamils, he said.
V Janakiraman and Thirugnanasambandam, who had been making efforts for establishing the Tamil Chair at the varsity, had taken up the matter with Jayalalithaa and sought the government's help, he said.
Subsequently Jayalalithaa included it (to extend assistance to such an initiative) in the list of promises as part of AIADMK's election manifesto last year, he recalled.
The move will help in taking up research work on India based on Tamil language, enabling more students pursue research on Tamil culture, and bringing Tamil archives being maintained in US libraries under the research ambit, he said.
These will ultimately help the world know about the richness of Tamil language, the Chief Minister added.
