Russia and Turkey are taking steps to improve ties and work together in Syriaafter talks between the Russian and Turkish leaders.Turkish President Recep Tayyip Erdoganmet with Russian President Vladimir Putin in Saint Petersburg on Tuesday.Putin announced that Russia would begin easing sanctions designed to punish Turkey.The move would include restarting work on energy projects, such as work on Turkey's first nuclear power centerand a pipeline from southern Russia to the Black Sea.Russian officials said trade with Turkey could return to normal by the end of the year.The Hurriyet Daily News reported that the two sidesagreed to set up a direct telephone linebetween their militaries to prevent incidents in Syrian airspace.In November, Turkey shot down a Russian jet bomber near its border with Syria.Turkish officials accused the airplane of violating Turkish airspace.Russia denied the plane had been over Turkeyand called the act a planned provocation by supporters of terrorism.Russian officials answered the Turkish moveby ordering economic and diplomatic sanctions on its neighbor.In June, the Turkish president apologized for the incident,and the two sides agreed to hold direct talks.Russia supports the government of Syrian President Bashar al-Assad,while Turkey has supported groups trying to force him from power.The two sides have been fighting in Syria for more than five years.The violence has caused more than 2.5 million refugees from Syria to enter Turkey.Russia increased its involvement in the fighting last yearby carrying out bombing raids on Syrian rebel targets.Some observers, however, are questioning how much Turkey and Russia can cooperate.They say the two sides have little common ground in Syria's civil war.Military expert Alexander Golts says,"I think until now they have no clear decisionbecause it's clear that their interests are colliding in Syria."Golts currently works as a visiting researcher at Uppsula University in Sweden.However, the talks between the two presidents could be a signthat Recep Tayyip Erdogan wants compromise on the issue of Syria.The meeting also could show Western alliesthat the Turkish leader has several options available to him.Ishat Saetov directs the Modern Turkey Studies Center in Moscow.He said Erdogan was surprised by the effect Russian economic actions had on Turkey.The "loss of more than 4 million tourists made quite a blow on the economy," he said.Although the two countries disagree about Syria,Russia supported Erdogan after members of Turkey's military attempted to overthrow his government.The United States and European countrieshave criticized Turkey's reaction to the failed overthrow attempt.The Turkish government has arrested thousands of people, including many reporters.Turkey accuses clergyman Fethullah Gulen of plotting the failed coup.Gulen lives in the American state of Pennsylvania.Turkish officials want him extradited to Turkey for trial.The U.S. government has refused to do this without evidence.Turkey is also in disagreement with Europe over paymentsfor accepting Syrian refugees and other migrants.The government wants the European Union to permit visa-free travel for Turkish citizens."Syria is one of the issues that Erdogan may trade upon," said Saetov.He said Erdogan may be willing to negotiate on the issue.Yet Turkish officials say Assad must leave office eventuallyand that Russia will not take the place of its western allies.
