At a meeting in Tashkent, Uzbekistan, last Sunday, the leaders of the five Central Asian states — Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan and Tajikistan — made an important decision that could have geopolitical ramifications for Eurasia. At the Seventh Consultative Meeting of the Heads of State of Central Asia, also referred to as the C5, the leaders agreed to formally add Azerbaijan to the format. Going forward, this body will be known as the C6.
