Russian President Vladimir Putin arrived in Iran on Tuesday, his first international trip across the borders of the former Soviet Union since the start of the invasion of Ukraine.
Putin met with Iranian President Ebrahim Raisi in Tehran and with Turkish President Recep Tayyip Erdogan. He also met with Iran's Supreme Leader Ayatollah Khamenei on Tuesday.
"I am very pleased to be in the hospitable Iranian soil. We can boast of record figures in terms of trade growth," Putin said in a bilateral meeting with Raisin.
"We are strengthening our cooperation on international security issues, making an important contribution to the solution of the Syrian conflict", he said further.
Raisi also hailed an "important" commitment to security cooperation between the two countries, saying both countries had "good experience" in the fight against terrorism.
Also on Tuesday, Iran's national oil company signed a $40 billion deal with Russia's state gas company Gazprom, according to a statement from Shana, the news agency for Iran's oil ministry.
The deal includes the development of Iranian gas fields and the construction of new gas export pipelines.
