The Rise of China in Central Asia： The New Silk Road Diplomacy

China＇s relationship with Central Asia has grown manifold since the foundation of Shanghai Five in 1996, which in June 2001 became the Shanghai Cooperation Organisation. The impetus to the relationship has further been accen- tuated when China-Russia friendship treaty was signed in July 2001. The US-led war in Afghanistan against Taliban and A1-Qaeda has yet again cemented Chinese position in Central Asia, and the recently concluded Belt and Road Initiative （BRI） has undeniably dramatically underscored the strategic value of Central Asia to the west and has opened up possibilities for Chinese security, political and economic interests. Geostrategically enmeshed with Central Asia, China will remain an integral and increasingly influential player in Central Asia. This research paper contextualises China＇s emergence and interests in Central Asia discarding the much talked about great game thesis and asserts by analysing the rise of China in the region as an unmatched and unchallenged power which has been testified once again with the recent BRI of Beijing.

Central Asia has long emerged as a hotspot for both the regional and extra-regional powers for two main reasons:its geopolitical location in the middle of Eurasia between Europe,South Asia,the Middle East,Russia and China,and their abundant and mostly unexplored natural *** on huge untapped hydrocarbon potentials the Central Asian geographical entity in recent years has offered enormous opportunity and appeal for global countries and emerged as a grand chessboard for regional and extra-regional *** is one such new pole in the new great game without which any geopolitical and geo-economic debate on Central Asia would be *** this prelude,this article attempts to analyse China's rise in Central Asia and its strategies to strengthen its position in the heartland region by discarding the much-hyped great game thesis and argues that China’s rise is unparallel and unmatched as testified by the recent Belt and Road Initiative of Beijing.
