Joining me in the studio right now is Mr Liu Shinan, senior columnist with China Daily. Welcome. He is about to talk more on the uniqueness and preservation of cultural heritages in Asia.

Q1: Mr. Liu, Asia's long history and rich cultures have made it home to many heritage sites. How would you define their distinctiveness compared to those in other parts of the world?

Q2: Despite their importance, terror attacks, political turmoil and natural disasters are threatening the existence of these sites. Many countries have signed the international treaty of preservation. What are some effective ways to protect them from harm?
