DUSHANBE (Reuters) - Tajikistan, a former Soviet republic bordering Afghanistan, has rejected requests by foreign powers to allow them to set up military bases on its territory because it does not want to upset Russia, its president said on Tuesday.
Central Asia has become an important alternative transit route for shipments of non-lethal supplies for NATO forces in Afghanistan but international powers have not made any public requests to open military facilities there.
Tajik President Imomali Rakhmon said he had been approached by several countries seeking permission to set up bases in his impoverished mountainous nation which also borders China.
"Russia is the main strategic partner and our natural ally, and I hope that it will always be like this," Rakhmon said in the Tajik capital Dushanbe.
"On my desk, I have a folder containing offers from other states, promising wonders in return for opening their military bases and other facilities, but we are not even considering them," he said, without naming the countries.
Relations between Russia and Tajikistan have deteriorated recently, particularly after a Russian pilot was jailed in Tajikistan last November, prompting speculation that Tajikistan might seek closer ties with Moscow's rivals in the region.
The pilot and his Estonian colleague were amnestied shortly afterwards but the case has contributed to sour diplomatic ties.
NATO forces are due to pull out most of their combat troops from Afghanistan by the end of 2014 and have not officially voiced any plans to stay in the region beyond that timeframe.
Russia, for its part, says it opposes a long-term Western military presence in Afghanistan while also expressing fears that the NATO pullout could contribute to the spread of drugs and Islamist militancy toward its southern borders.
Rakhmon's secular government enjoyed Moscow's support during a civil war between his forces and the Islamist opposition in 1992-97. Tajikistan is still home to around 6,000 Russian troops at a Soviet-era military base which is deployed in three towns.
Russia wants to renew the lease at Base No. 201 for another 49 years when it expires later this year. The base includes a satellite-tracking facility in the Pamir mountains.
Immigration is also a big issue in Tajikistan's relations with Russia, home to more than a million Tajik migrant workers.
The pilots' case has triggered a crackdown on Tajik migrant workers in Russia, with anti-immigration nationalist parties demanding tougher visa rules for Tajik citizens - a worrying signal for a country relying on remittances to make ends meet.
Last year, Tajik workers sent home around $3 billion in remittances, almost half of Tajikistan's gross domestic product.
"We respect the interests of our strategic partner, but our partner should in its turn respect its ally," Rakhmon said. "It is time (for Russia) to finally determine its position and always be with its partner in its hard times."
