Cambodia's Angkor Wat temple complex is one of the most important archeological sites in Southeast Asia, and a major draw for tourists. The United Nations' cultural arm, UNESCO, has set up a wide range of programs to safeguard the site and its surroundings. Over the past two decades, China joined international efforts to help Cambodia preserve the complex.
The Angkor Wat temple complex is one of Cambodia's most important cultural landmarks. It reflects the nation's Khmer history and culture.
The ruin was listed as a UNESCO World Heritage site in 1992. It was also placed on the List of World Heritage in Danger at the same time, as looting, a declining water table, and unsustainable tourism made their mark.
Since 1998, China has participated in international efforts to help Cambodia preserve the historic ruins. Together with local officials, Chinese experts spent eight years successfully restoring Ta Keo Temple -- one of the most culturally representative buildings at the complex.
Only a few machines were used in the project, to better repair and restore the relics. Another expert team from China successfully restored Chau Say Temple between 1998 and 2008, using just their hands and simple tools.
Now the restoration project is nearing completion, many areas of the complex have been re-opened to the public.
Tourism is Cambodia's second most important industry. And the Angkor ruins are definitely a trademark of Cambodian tourism. It's also a vital source of income for many locals.
The restoration project also provides a lifeline for many locals. More than 140 villagers are working on the project.
