Meanwhile, public awareness-building activities will go a long way towards ensuring the protection of China's natural and cultural heritage.

"When people around the globe can better understand the essence of our cultural legacy, they will naturally appreciate the value of it and support cultural relic conservation. And by appreciating Chinese culture, friendship and trust will be built," Liu said.

In the future, China will provide assistance to countries, including Cambodia, Nepal and Kazakhstan, to ensure the protection of their natural and cultural heritage. "We will share our ideas and experiences with the world," Liu said. "China will shoulder more responsibilities in preserving the wealth of human civilization."
