Chinese President Xi Jinping on Tuesday urged the government to strike a balance between the conservation of cultural relics and economic development.Xi said the balance is difficult to strike in a country that is urbanising at such a fast pace, Xinhua news agency reported.He called cultural relics "a valuable legacy from our ancestors", stressing that conservation will benefit future generations.Xi urged party and government departments to keep in mind that this conservation is part of their official duties, and suggested that "private sectors should be mobilised and involved in the effort".
