Dmitry Medvedev said after a meeting with his Tajik counterpart, Emomali Rakhmon, that the two leaders had agreed that the Gissar airfield, located around 20 km west of the capital Dushanbe, would be used by the Russian Defense Ministry.
"Russia will also complete the construction of some partially-built facilities," he said.
The meeting, which followed a two-day summit of the Shanghai Cooperation Organization recently held in the Tajik capital, is also reported to have resulted in a joint statement on further expansion of military ties between the two countries.
Russia and Tajikistan are members of the Collective Security Treaty Organization (CSTO) also comprising Armenia, Kazakhstan, Kyrgyzstan, Uzbekistan, and Belarus.
The post-Soviet security alliance is scheduled to meet on September 5, where the parties are widely expected to work out a joint position on the latest conflict.
