Recep Tayyip Erdogan says Turkey and Russia can rebuild their damaged ties and make the two countries even closer after talks with Vladimir Putin.
Calling the Russian leader his "dear friend", President Erdogan said Turkey is ready to implement a natural gas pipeline project with Russia and a deal to build Turkey's first nuclear power plant.
Mr Putin, in his turn, said that the flow of Russian tourists to Turkey - halted after the downing of a Russian jet by Turkey in November - will resume.
Mr Putin added that he and Mr Erdogan will have a separate discussion on Syria later on Tuesday involving top military and intelligence officials to search for common ground in the crisis, where Moscow and Ankara have backed the opposing sides.
While Moscow has backed Syrian President Bashar Assad throughout the nation's civil war and further bolstered that support by launching an air campaign last September, Turkey has pushed for Mr Assad's removal.
Previously close ties between Moscow and Ankara broke down after a Turkish jet shot down a Russian warplane at the Syrian border, an incident that Mr Putin had described as a "treacherous stab in the back."
Relations remained at a freezing point for seven months until Mr Erdogan met the Russian demand for an apology over the incident.
Mr Putin then ordered his government to start rebuilding ties with Turkey, and when Mr Erdogan faced a botched coup attempt on July 15 the Russian leader quickly offered his support.
President Erdogan particularly mentioned Mr Putin's gesture, saying it "gladdened me, my colleagues and our people".
Analysts say that Mr Erdogan may now be hoping to play the Russian card to strengthen his hand in disputes with the United States and European Union.
Turkey is pressing the United States hard to extradite Turkish cleric Fethullah Gulen, whom the government blames for the failed coup. Gulen denies the claims.
The dispute has strained US-Turkish ties, with some Turkish officials implying the US could have been behind the coup. Washington has denied that.
Speaking after the talks with Mr Putin, Mr Erdogan reaffirmed his claim that Mr Gulen was behind the coup - but did not touch on Ankara's demand for his extradition.
The failed coup saw renegade Turkish military officers using jets, helicopters and tanks to try to take power in a night of violence that left more than 270 people dead.
Since then, about 18,000 people have been detained or arrested and nearly 70,000 people suspected of links to Mr Gulen have been suspended or dismissed from the civil service, judiciary, education, health care and the military.
European officials and rights groups have expressed concern over the crackdown - statements that have vexed Turkish authorities. Ankara has accused the West of failing to show due support for a democratically elected government.
In contrast, Mr Erdogan praised Mr Putin for offering his support after the coup and said that "we are strongly determined to take our relations to the pre-crisis and even higher level".
Mr Putin responded in kind, saying that "higher interests of our peoples, our nations require the restoration of our relations."
