Tourism in Cambodia has developed rapidly in the last decade. There is strong evidence that Cambodian tourism has developed primarily on the basis of the comparative advantage of the Angkor Wat temples.

However, Cambodia need to diversify beyond the key attraction of Angkor Wat in Siem Reap and business tourism in Phnom Penh.
