MOSCOW — Russia signed Tuesday a string of bilateral agreements with Iran as President Vladimir Putin hosted his Iranian counterpart Hassan Rouhani for his first official visit to Moscow.

The meeting between Putin and Rouhani, who have grown closer through their mutual support of Syrian president Bashar al-Assad, mostly focused on flourishing economic ties in the fields of energy and industry.

Putin said in televised comments after the meeting that trade between the countries had “grown more than 70 percent” last year.

“This is truly a good result considering that it was achieved in unstable global conditions and amid persistent volatility on the commodity and currency markets,” Putin said.

A joint statement published by the Kremlin said that “special attention” had been paid to cooperation in energy, with both sides pledging to continue efforts to stabilize the international market. In addition to cooperation on Syria, energy and defense ties have deepened between Iran and Russia in recent years.

Russia is to build nine of Iran’s 20 proposed nuclear reactors and has emerged as a long-term arms partner, supplying Tehran with its S-300 air defense missile system. The relationship has blossomed under Rouhani despite the countries having a complicated history over territory, oil and communist ideology. Rouhani is looking to boost Iran’s economy ahead of elections in May, in which he is expected to stand for a second term. Putin also hailed the countries’ role in ensuring peace in Syria, where both Russia and Iran have shored up Assad.

The joint statement said that cooperation between Tehran, Moscow and Ankara to bring the Syrian regime and armed rebels to the negotiating table was “an important step on the road to the success of the Geneva negotiations under the auspices of the United Nations.” Rouhani said that Moscow and Tehran had “begun effective cooperation” in countering “terrorists” in Syria, in a speech at Moscow State University where he was granted an honorary doctorate.
