Since their independence in 1991, the states of Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan) have become increasingly important as regional and international actors. They have joined the United Nations (UN) as well as regional organizations, such as the Commonwealth of Independent States (CIS), the Collective Security Treaty Organization (CSTO), the Shanghai Cooperation Organisation (SCO), and the Eurasian Economic Union (EAEU). International law has played an important role in the processes of state-building and integration these countries have undergone, yet it has not always been consistently accepted as a policy tool and academic discipline. In particular, building a stable nexus between the practice of international law and academic research on the subject remains a challenge. This chapter provides an overview of Central Asian practices and doctrines of international law with a focus on international peace and security, international organizations, international environmental law, human rights, international humanitarian and criminal law, and international investment arbitration. It concludes with recommendations for more successful promotion and implementation of international law in the region.
