Today Cambodia has a population of over 15 million, and faces numerous challenges. Important sociopolitical issues includes widespread poverty, pervasive corruption, lack of political freedoms, low human development, and a high rate of hunger, but Cambodia has one of the fastest growing economies in Asia with growth averaging 6 percent over the last decade. Agriculture remains the dominant economic sector, with strong growth in textiles, construction, garments, and tourism leading to increased foreign investment and international trade.
In the past, The Khmer Empire
, the predecessor state to modern Cambodia, was a powerful Hindu-Buddhist empire in Southeast Asia. The empire, which grew out of the former kingdoms of Funan and Chenla, at times ruled over and/or vassalised most of mainland Southeast Asia, parts of modern-day Laos, Thailand, and southern Vietnam.
Its greatest legacy is Angkor, in present-day Cambodia, which was the site of the capital city during the empire's zenith. The majestic monuments of Angkor—such as Angkor Wat and Bayon—bear testimony to the Khmer Empire's immense power and wealth, impressive art and culture, architectural technique and aesthetics achievements, as well as the variety of belief systems that it patronised over time. Satellite imaging has revealed that Angkor, during its peak in the 11th to 13th centuries, was the largest pre-industrial urban centre in the world.
The beginning of the era of the Khmer Empire is conventionally dated to 802 CE. The empire ended with the fall of Angkor in the 15th century. From Wikipedia
