Russian President Vladimir Putin is to hold a series of high-profile meetings with Turkish, British and Saudi leaders, among others, as part of his schedule for attending a summit in China in early September.

Yury Ushakov, a Kremlin aide, told reporters on Tuesday that Putin will hold talks with Turkish President Recep Tayyip Erdogan on September 3, when he is in Hangzhou, China, for the summit of the group of 20 world major economies, known as G20.

Ushakov said Putin’s meeting with Erdogan will take place as the “process of normalization of relations between the two countries is under way.”

Russia downgraded ties with Turkey last November, when Ankara shot down a Russian jet near the Syrian border. Relations began to improve in July after Ankara offered an apology as demanded by Putin. The two met this month in Russia, with reports suggesting they narrowed gaps on the conflict in Syria.

Ushakov said Putin will also hold a meeting with Saudi Arabia's powerful deputy crown prince, Mohammed bin Salman, to discuss the crisis in Syria. He would not elaborate but said the meeting will come on September 4, the day when the Russian president will also hold an important meeting with British Prime Minister Theresa May to discuss a need for “a new impetus in bilateral relations.”

The official said a trilateral meeting of leaders from Russia, Germany and France, which had previously been agreed to discuss the conflict in Ukraine, was called off and instead Putin would meet separately with French President Francois Hollande and German Chancellor Angela Merkel on September 4 and 5, respectively. He noted that the sensitive meeting on Ukraine was cancelled because of new tensions that have emerged over Crimea, a former Ukrainian territory which rejoined Russia following a referendum in 2015.

Putin will also hold a much-anticipated meeting with Egyptian President Abdel Fattah el-Sisi, who will be in China as a guest to G20, Ushakov said.
