According to IRNA, Aliyev told Iran's deputy foreign minister and special envoy to the Caspian affairs Mehdi Safari that all-out expansion of cooperation between Tehran and Baku is of high significance for the two sides.

He said the venture economic projects and growing cooperation in the industries, transportation, energy, power and gas domains signal drastic changes in ties between Iran and Azerbaijan.

Safari said growing relations between Iran and Azerbaijan indicate strong will of the two countries' leaders for continuation and promotion of the ties.

The two sides also hoped for finalization of the Caspian Sea legal regime in near future.

Safari arrived in Azerbaijan on Thursday to hold talks with Azeri senior officials on bilateral, regional and international issues as well as on the Caspian Sea related subjects.
