The country will focus on heritage protection issues including solving problems of traffic passing through the sites, efficiently easing potential threats that result from the rising number of tourists, and drafting plans on risk management and hazard prevention of the heritage, Liu said.

The country will further conduct archaeological research on Liangzhu City and expand the excavation area by a step-by-step archaeological plan, in the meantime, improve the display of the cultural heritage and demonstrate the value of the cultural site in a more professional, vivid and in-depth way, Liu said.

"Archaeological Ruins of Liangzhu City is a major archaeological discovery of China in the 20th century and an important cultural site that witnessed the 5,000-year civilization of the country," said Liu.

It not only opens a unique window for the world to know ancient and contemporary China in a true and panoramic perspective, but also enhances the influence of Chinese culture, according to Liu.
