After attracting more than 100,000 tourists from India since January, the government expects that number to hit 500,000 by the end of the year.
Government spokesman Thanakorn Wangboonkongchana said on Sunday they could bring in revenue of 22.5 billion baht.
The Tourism Authority of Thailand (TAT) is aiming to attract 3,000 Indian arrivals a day through various promotions, including opening new routes between India and different parts of the country, such as an India-Chiang Mai route, he said.
