There was much to discuss just over a year after the end of the war, including ongoing border tensions, plans to reopen borders and transportation, and the fate of Armenian prisoners.
The question of whether Uzbekistan should join the Russia-led Eurasian Economic Union, with its single market of 184 million people, has provoked fierce debates.
The announced deals could be significant, and come shortly after the two sides patched up a period of serious political tensions. But many details remain unclear.
Officials in Karabakh are remaining tight-lipped about Iranian fuel imports, and say that Baku is using the issue as a pretext to drive out the region’s Armenian population.
Meanwhile, Azerbaijan released two truck drivers whose arrest sparked the tensions, while Iran agreed to forbid trucks from entering Karabakh from now on.
