Russian President Vladimir Putin has officially ratified a comprehensive strategic partnership agreement with Iran, according to an official document published online Monday.

The treaty was initially signed by the Russian president and his Iranian counterpart, Masoud Pezeshkian, on Jan. 17 following bilateral talks in Moscow.

Russia's State Duma, or the lower house of parliament, ratified the treaty on April 8, and Russia's upper house of parliament, the Federation Council, approved the agreement on April 16.

According to the agreement, the two countries aim to deepen and expand relations in all areas of mutual interest, strengthen cooperation on security and defense, and closely coordinate activities at regional and global levels, which corresponds to a long-term, comprehensive and strategic partnership.

During a press conference following the Russia-Iran talks in January, Putin stressed the significance of the agreement, saying it outlines "ambitious goals" for deepening long-term cooperation.

He said the treaty is designed to create stable conditions for the sustainable development of both countries and the whole Eurasian region.
