Hangzhou in East China's Zhejiang province set up its first alliance for world heritages on June 13 to mark Cultural and Natural Heritage Day, which falls on the second Saturday of June every year.

As a city with a long history and deep cultural roots, Hangzhou was widely recognized as a world heritage city because three of its cultural treasures – West Lake, Beijing-Hangzhou Grand Canal and Liangzhu Archaeological Site – have been inscribed on the UNESCO World Heritage list.

In recent years, the city has played an active role in protecting historical and cultural sites while achieving economic and social development in a number of areas.

The alliance will further Hangzhou's efforts to preserve cultural relics, improve local governments, raise awareness of where the relics are located, and encourage the research and promotion of the relics.

Activities entitled "Making Cultural Relics Come Alive" were popular in the city and encouraged people to cherish and protect the treasures.

The ruins of Tianmu Kiln, ancient seawalls of the Qiantang River and ancient imperial city of the Southern Song Dynasty (1127-1279), all located in Hangzhou, are also making preparations to be included on the UNESCO World Heritage list as soon as possible.
