In Saudi Arabia for the first time there has arrived the President of Russia Vladimir Putin.The main topic of conversation of the Russian and the Saudi leader was the largest oil deal worth $ 10 billion and rapidly changing situation in the middle East. Following the recent cooling of relations between the US, Iran, Turkey and other countries began to open up the political ambitions of Russia in the middle East.October 14, Putin held talks with king of Saudi Arabia Mohammed bin Salman al Saud on ways of strengthening bilateral relations. Putin noted that Russia considers it important to develop friendly and mutually beneficial relations with Saudi Arabia. Salman also expressed the hope that cooperation with Russia will help to strengthen regional security and to combat terrorism.On this day, the sides signed over 20 agreements on cooperation in such fields as energy, petrochemicals, telecommunications and artificial intelligence, as well as contracts of long-term cooperation between OPEC and outside the organization oil-producing countries. According to Saudi media, the total cost of the agreement amounted to about $ 10 billion.According to reports, “Saudi information Agency” (SPA), the crown Prince Mohammed bin Salman discussed with Putin the situation in Yemen and Syria, and the need to fight extremism and terrorism. Bin Salman said that the cooperation between Russia and Saudi Arabia in the field of energy helps to preserve stability in the region.Last time Putin was in Riyadh in 2007. Now, the two countries jointly control the supply of oil and keep high prices on them, but their position in the regional conflicts in the middle East are very different. In the Syrian civil war Moscow has always been on the side of Bashar al-Assad, and Saudi Arabia supported the opposition. Russia is continuously strengthening the ties with Iran, which is not the true US ally — Saudi Arabia.Despite the obvious differences, Russia has long been trying to entice Saudi Arabia to their side. Due to a mysterious incident with the death of a Saudi journalist Jamal Khashoggi the Saudi Embassy in Turkey, on the summit of “Big twenty”, held in December last year in Argentina, all defied the crown Prince, and only Putin kindly talked with him.Putin’s visit took place at the right time. Last week trump announced the withdrawal of troops from the North-East of Turkey, thus betraying the Kurds. In relations between the US and Iran and show no signs of improvement. All this has forced to strain American allies in the middle East. Russia immediately pushed into the “gap” opened between the United States and allied middle Eastern countries.In an interview to Saudi media on 13 October, Putin said that Russia is building bilateral relations solely on the basis of active interaction, not against allies of any country.In 2015, Russia began to declare publicly return to the middle East. In September 2015, at the request of the Syrian government, Russia has sent troops to help in the fight against extremists and the return of the lost lands. At the end of 2017, Putin announced about the withdrawal of troops, with the exception of the air force base in Hamima and a naval base in Tartus.Before the trip, Putin reiterated that Russia is able to positively influence the situation in the Persian Gulf. After leaving Saudi Arabia, he will go on a state visit to the UAE.According to the Washington post, introduction to the political center of the Middle East — part of the strategy of Moscow. Not so long ago Putin said that at the beginning of next year will go to Israel for a visit. The Prime Minister Benjamin Netanyahu visited Russia last month for a few days before the election.Saudi Arabia, UAE and Israel perceive trump as an important figure to restore relations with the United States. However, the complication of the situation in the Persian Gulf following the withdrawal of the U.S. from an Iranian nuclear deal which the country was secretly approved, made them begin to worry.Last month there was an attack on two oil facility in Saudi Arabia, responsibility for which was assumed by the Houthis from Yemen. However, many Western countries headed by the USA and blame Iran. These attacks also raised some doubts in the actions of the UN security. Weapons purchased from the United States hundreds of billions of dollars, did not show himself at the crucial moment. Saudi Arabia has always been a major buyer of American weapons, especially after the coming to power of trump. A few months after the inauguration of the new President of the USA, Saudi Arabia promised to buy weapons in the amount of 110 billion dollars.After the attack on oil installations Putin began to actively offer Saudi Arabia anti-aircraft missile systems s-300 and s-400. If the country bought these SAMS, Washington began to worry. The Ministry of defense said that will add to Saudi Arabia 3 thousand soldiers, two regiments of fighters, two calculations SAM “patriot” and a single calculation of a missile complex long-range interception THAAD, provided that Saudi Arabia will take care of all expenses.Trump’s intention to withdraw its forces from Syria have also become a good opportunity for Russia to enter the arena. The Kurds, deprived of all support, was opposed to coming up close a huge Turkish army. They have no other choice but to side with the Syrian government. October 13, the Kurds announced the conclusion of an agreement with the Syrian government, which will have its forces along the Turkish border to help the “Syrian democratic forces” (SDF) to “contain the intrusion” and to return lands seized by Turkish troops and they have supported the opposition. According to Kurdish intelligence officer, Russia again played an important role in the negotiation process.Russia not only maintained good relations with the Kurds and Syria but with Turkey. In July this year, Turkey bought from Russia the s-400, thereby causing a stir among his fellow NATO and anxiety in the United States.American broadcasting company (CNN) commented as follows: “the Countries participating in NATO bought Russian weapons specifically to shoot down missiles launched from American fighters, it’s up to no good”. The newspaper “Los Angeles times” reported that the decision to purchase the s-400 could mean “the end of the 70-year-old military cooperation between Ankara and Washington.”Turkey has always fluctuated between the US and Russia, she was originally against the regime of Bashar al-Assad, and in 2016, after the failed coup began to get closer to Russia and even created together with Russia and Iran the mechanism of negotiations in Astana.It is undeniable that the recent U.S. actions in the middle East have forced many countries in the region to see Russia as a reliable “fallback”. However, according to the newspaper “Washington post” that Russia is behind the USA in economic and military power. Five years ago the Russian economy was seriously damaged and is still unable to fully recover from Western economic sanctions caused by the Ukraine crisis, besides, as the country was hit by the recent military conflicts. Therefore, s-400, which is so proud of Russia, has not been tested in real combat conditions.Middle East countries are not in a hurry to turn away from US and go to Russia. The Saudi diplomat, Adel al-Jubeir mentioned in an interview that maintaining close ties with Russia will not affect relations between Saudi Arabia and the United States. The country will be able to develop friendly relations with Russia, while maintaining close strategic cooperation with the United States.
