Both Russia and, increasingly China, have been viewed as the main revisionist challengers to the liberal international order. The main vehicle for these counter-ordering efforts have been new economic and security regional organizations established by Moscow and Beijing to project their agendas and check the influence of Western counterparts. For Russia, this has included founding the Collective Security Treaty Organization (CSTO) as a regional security alternative to NATO, while in the economic sphere Russia has pushed for ever-increasing regional integration through the Eurasian Economic Union. For China, the most important of these new organizations is the Shanghai Cooperation Organization (SCO) founded in 2001. And in 2016 China also founded the Quadrilateral Cooperation and Coordination Mechanism (QCCM), established to promote regional anti-terrorist coordination and security cooperation between Tajikistan, Afghanistan and Pakistan. Around the same time investigative reports revealed that Beijing concluded an agreement to establish a military base in Tajikistan, with Chinese troops given the authority to patrol large swathes of the Tajikistan-Afghanistan border.
