Over the past three decades, China has been part of a UNESCO led group of 30 countries working to restore Angkor Wat. Chinese experts from a variety of fields have already completed the restoration of two temple sites, and preparing for a new project. These restoration efforts have helped make a significant economic contribution to Cambodia's tourism industry, but they have also helped preserve a site that embodies important elements of Cambodian culture. The ancient Cambodian martial art of Bokator is one such element, and it is depicted on bas-reliefs at the site, inspiring the younger generation to help keep this tradition alive.
