Significance
The Taliban victory creates threats and some opportunities for Central Asian republics, three of which -- Tajikistan, Uzbekistan and Turkmenistan -- border on Afghanistan. All except Tajikistan have indicated they will work with the new Afghan authorities.
Impacts
Russia and Central Asian states, except Tajikistan up to a point, will not back anti-Taliban resistance groups.
Weak Afghan governance creates more scope for heroin trafficking through Central Asia.
Although China is the more important economic player in Central Asia, it will defer to Russia on security matters.
