Abstract:

Constructing the Silk Road economic belt and getting through the 21st century Sea Silk Road are the important national
opening strategies for China now. "One Belt and One Road", the new national opening strategy, is closely related to Yunnan which is the front edge and window of national opening southwest strategy and enjoys prominent status in whole macro-geography. Based on the study of the Silk Road, Yunnan happens to be on the joint point of the Southern, Northern and Sea Silk Road. In the "One Belt and One Road" strategy, Yunnan serves as an important joint point of connecting these "three roads" "two oceans", and "two continents" with its prominent gateway function in the strategy of opening to west. Revitalizing the Southern Silk Road is the inevitable choice of China's strategy in Indian Ocean and the objective requirement of constructing the economic belt among Bangladeshi, China, India and Myanmar. It is a new change in geopolitics of turning Yunnan's backward position in the Reform and Opening-up Policy into front edge in national strategy of opening to west. With the good basic condition in the strategy of opening to west, Yunnan is able to take great
responsibilities in national strategy "One Belt and One Road". People in Yunnan have to take the historical responsibility of playing a
leading role in national overall strategic arrangement.

Key words: "One Belt and One Road", the Silk Road, national opening strategy, Yunnan, status and functions
