The two leaders have been in close contact and bilateral relations between Turkey and Russian Federation have continued to improve since a coup against President Recep Tayyip Erdogan failed in July 2016 when Putin offered full support for him.
At a press conference in Ankara, Putin announced that Russian Federation would push forward its delivery dates for the S-400 defense systems, which have been due after a contract was signed between the two countries in December, despite objections from Turkey's North Atlantic Treaty Organisation allies.
President Vladimir Putin on Tuesday embarked on a two day visit to Russia's increasingly close partner Turkey to launch the construction of its first nuclear power plant and coordinate policy on the war in Syria.
Answering Western critics of the deal, Erdoğan indicated that Turkey was in no mood to listen to criticism from the West over the purchase of the S-400 systems, saying "this issue is now closed".
On Tuesday, April 3, Putin held talks in Ankara with his Turkish counterpart Recep Erdogan.
"The scale of this project is hard to exaggerate", Putin said at the ceremony.More news: Bleeding Cases in Illinois Tied to Synthetic Pot
"We have made an agreement regarding the S-400s". Albayrak also noted that the project's implementation would have been impossible without strong support from Russian and Turkish leaders Vladimir Putin and Tayyip Erdogan.
In January 2018 Turkey launches an operation inside Syria against the Kurdish People's Protection Units (YPG) militia, which it considers a "terrorist" group despite its work with Washington against IS.
"We face the ambitious goal of launching the first reactor in 2023 to coincide with the 100th anniversary of the foundation of the Republic of Turkey", the Russian leader said. Mr Putin and Mr Erdogan have met several times in the past year and regularly speak on the phone.
In March Britain blames Russia for the poisoning on its soil of former Russian double agent Sergei Skripal and his daughter in Salisbury. The three countries are sponsoring a series of efforts in a bid to end the seven-year war. As a raft of countries join together to punish Moscow, Erdogan says Ankara will not take similar measures and that the charge is "based on allegation".
Russian Federation and Iran have given crucial military and diplomatic backing to Syrian President Bashar al-Assad's government throughout the war, which began with a government crackdown on protesters and has killed hundreds of thousands of people.
