In The Economist special report on China and the US called 'Overkill' where the author James Miles postulates the opinion that China is piling up more weapons than it appears to need, Mr Miles also writes about the need for China to develop its soft power:
"Soft power was mentioned for the first time by a Chinese leader in public in 2007. Culture, said Mr Hu [Jintao, China's president IP Dragon] (oblivious, it seemed, of the cold-war overtones of his remarks), was of growing significance in the “competition in overall national strength”. China should therefore “enhance culture as part of the soft power of our country”."
