Editor's note: During his visit to Kazakhstan in September, President Xi Jinping proposed that China and Central Asia join hands to build a Silk Road economic belt to boost cooperation. The idea has been widely echoed in Central Asian countries, becoming an encouraging blueprint for Chinese areas along the Silk Road that has linked Asia and Europe for more than 2,000 years. In the next three weeks, China Daily reporters will travel through the belt. They will show the progress and expectations of the countries, businesses and peoples on the route.

The Silk Road economic belt provides a historic opportunity for the development of all Asia, but regional cooperation still faces challenges that require countries to enhance mutual trust and increase communication and cooperation, a senior Foreign Ministry official said on Wednesday.

"Reviving the Silk Road economic belt is not only needed for China's economic development, given that China has uneven development in our eastern and western regions, but it is also in the interests of other Asian countries," said Liu Jianchao, assistant minister of foreign affairs, at the Asia Cooperation Dialogue Forum on Silk Road Cooperation.
