In recent years, Bangladesh, India, Indonesia, Thailand and Vietnam have enhanced their tourism industries in interesting and diverse ways. This has boosted public infrastructure in several areas in these five countries and has led to increased employment opportunities among their citizens. Most importantly, it has paved the way for a new and growing industry besides agriculture, which has traditionally been the predominant sector in each of these countries. The tourism sector contributes about 2.3% to the overall GDP of Bangladesh, 6% to India, 3% to Indonesia, to Thailand, and 5.8% to Vietnam.
