Russia is pushing to impose a direct fuel supply deal on the US's airbase in Kyrgyzstan that would allow it to force a rapid closure of the base once it is no longer necessary to support Nato operations in Afghanistan.
"Ultimately it's in the security interests of Russia for the US to be using this base for its operations in Afghanistan, but under a very, very strict mandate," said Ana Jelenkovic, Central Asia analyst at Eurasia Group.
"If Russia is able to monitor the destination of the fuel, it limits the ability of the US to stay there in the base long-term. It makes the Americans staying there at Manas contingent always on some Russian support."
This is not a deal that NATO and the US are probably keen to have happen, but it may be the only way to keep the US base at Manas supplied.
