Saint Petersburg - Russian President Vladimir Putin and Turkish counterpart Recep Tayyip Erdogan on Tuesday promised to reinvigorate ties after their first meeting since Ankara shot down a Russian warplane last November.Erdogan's visit to Putin's hometown of Saint Petersburg is also his first foreign trip since the failed coup against him last month that sparked a purge of opponents and cast a shadow over Turkey's relations with the West."We lived through a very complicated moment in the relations between our states and we very much want, and I feel our Turkish friends want, to overcome the difficulties," Putin told journalists at a joint press conference after the encounter.The Kremlin leader insisted it would take "painstaking work" and "some time" to return to previous trade levels as Russia looks to roll back a series of economic sanctions against Ankara, but both sides said they wanted to restart major energy projects hit by the crisis. Erdogan said that he hoped Russian-Turkish relations would become "more robust" and stressed how important it was that Putin offered his support after the coup. "We will bring our relations back to the old level and even beyond, both sides are determined and have the necessary will," he said. The shooting down of a Russian fighter jet by a Turkish F-16 over the Syrian border last fall saw a furious Putin slap economic sanctions on Turkey and launch a blistering war of words with Erdogan that seemed to irrevocably damage burgeoning ties.But in a shock reversal late June, Putin accepted a letter expressing regret over the incident from Erdogan as an apology and quickly rolled back a ban on the sale of package holidays to Turkey and signalled Moscow would end measures against Turkish food imports and construction firms.Now in the wake of the failed July 15 coup attempt, there are fears in Western capitals that Nato-member Turkey could draw even closer to Moscow - with Erdogan bluntly making it clear he feels let down by the United States and the European Union.Putin was one of the first foreign leaders to phone Erdogan offering support after the coup attempt and shares none of the scruples of EU leaders about the ensuing crackdown.Back to business? Relations between Turkey and Russia - two powers vying for influence in the strategic Black Sea region and Middle East - have historically not been straightforward. Yet before the plane downing crisis, Moscow and Ankara managed to prevent disputes on Syria and Ukraine harming strategic co-operation on issues like the TurkStream gas pipeline to Europe and a Russian-built nuclear power station in Turkey.Those projects were all put on ice with trade between the two countries falling 43% in January-May this year to $6.1bn and Turkey's tourism industry seeing visitor numbers from Russia fall by 93%.Now with Russia mired in economic crisis due to Western sanctions over Ukraine and low oil prices along with Turkey's outlook flagging, both men want to get business started again.Erdogan said that he now wanted to see the TurkStream project "done as fast as possible", while Putin said construction could start "in the nearest future".The Turkish leader also insisted that the two sides were once again targeting a very ambitious trade turnover of $100 billion by 2024.Skirting SyriaThe earlier uptick in relations between Turkey and Russia was built on a macho friendship between Putin and Erdogan, two combative leaders in their early 60s credited with restoring confidence to their nations in the wake of financial crises but also criticised for clamping down on human rights.But after such a bitter dispute - which saw Putin accuse Erdogan of stabbing Russia in the back and profiting from an illegal oil trade with the Islamic State group - it will take a lot for the pair to reheat relations.The two strongmen leaders conspicuously skirted one major issue dividing them and that lay at the heart of their falling out - the war in Syria. Putin and Erdogan said they would start discussing the conflict after the press conference but the Russian leader insisted both sides were committed to finding a peaceful solution. Russia is flying a bombing campaign in support of President Bashar Assad while Turkey is fiercely opposed to the Syrian leader. Erdogan insisted in an interview with Russian media ahead of the talks that Assad must still go - a position opposed by Putin - but said that the conflict could now become the focus for renewed cooperation between the two sides.
