Southeast Asia Treaty Organization [SEP] Cultural effects
In addition to joint military training, SEATO member states worked on improving mutual social and economic issues. Such activities were overseen by SEATO's Committee of Information, Culture, Education, and Labor Activities, and proved to be some of SEATO's greatest successes. In 1959, SEATO's first Secretary General, Pote Sarasin, created the SEATO Graduate School of Engineering (currently the Asian Institute of Technology) in Thailand to train engineers. SEATO also sponsored the creation of the Teacher Development Center in Bangkok, as well as the Thai Military Technical Training School, which offered technical programs for supervisors and workmen. SEATO's Skilled Labor Project (SLP) created artisan training facilities, especially in Thailand, where ninety-one training workshops were established.
