What to make of this?:
Azerbaijani Foreign Minister Eldar Mammadyarov has expressed concern about the opening of a direct land connection between Russia and Armenia via Georgia through the Larsi checkpoint. Azerbaijani’s concern is based on the fact that through this connection Moscow could supply Yerevan with military cargo designed for the 102nd Russian military base located in Gumri, Armenia. If Azerbaijan receives information that Armenia is being supplied with arms through this route Baku will immediately react and ask Tbilisi for explanations.
The Russian media reports that Baku is thinking of taking "adequate measures" against Georgia in response to the Upper Larsi checkpoint opening. Energy and investment projects and the issue of Abkhazia and South Ossetia may be affected by these.
For its part, Georgia says “No weapons or ordinance for Russian troops in Armenia will be allowed access” through the border checkpoint. Though, technically, that doesn't preclude allowing weapons for Armenia, that seems pretty unlikely. It seems to me more likely that this is the best pretext Azerbaijan could come up with to object to the opening of the border, whose closure was causing economic problems for Armenia. But maybe I'm missing something here?
