Thailand has been receiving increased competition ever since Laos, Cambodia and Vietnam opened up to international tourism in the 1980s and 90s. Destinations like Angkor Wat, Luang Prabang and Halong Bay now contest Thailand's former monopoly in the Indochina region. To counter this, Thailand is actively targeting niche markets such as golf holidays, or holidays combined with medical treatment. Thailand has also plans on becoming the hub for Buddhist tourism in the region.
