US President Donald Trump and his Russian counterpart Vladimir Putin agreed on Wednesday to hold a summit in a third country as US National Security Advisor John Bolton was received in Moscow. Presidential adviser Yuri Ushakov made the announcement after a meeting in Moscow between Putin and Bolton. The time, venue and other details of the summit will be announced jointly by the Kremlin and the White House on Thursday, Ushakov said. He said the summit would take place in a third country, but did not name it as part of the plan for a joint declaration with Washington. The site will be "very convenient for both us and the US side," he said. Bolton was received in Moscow with top honors: a lunch hosted by Foreign Minister Sergei Lavrov followed by a markedly courteous meeting with Putin at the Kremlin. "Your visit to Moscow gives us hope that we can at least take the first step to reviving full-blown ties between our states," Putin told Bolton at the Kremlin after the two smiled and shook hands for the cameras. "We never sought confrontation," Putin said, adding he regretted that the Russia-US ties were not "on top form". US-Russian relations have been strained by disagreement over the Syrian conflict, Russias annexation of Crimea, its involvement in eastern Ukraine and allegations of political meddling. Bolton, known for his hawkish reputation and tough stance on Moscow, said it was important to keep talking and complimented Putin on his handling of the football World Cup, currently taking place in Russia. "Even in earlier days when our countries had differences our leaders and their advisors met and I think that was good for both countries, good for stability in the world and President Trump feels very strongly on that subject," he said. Recently ties have been strained by a probe into alleged Russian meddling in the 2016 US presidential election and suspected collusion with the Trump campaign, as well as by the poisoning of a former Russian spy in Britain. "A lot of people have said or implied over time that a meeting between President Trump and President Putin would somehow prove some nexus between the Trump campaign and the Kremlin, which is complete nonsense," Bolton told a news conference later. "What must guide his (Trumps) conduct of American foreign policy is the pursuit of American national interests... He will do this regardless of political criticism at home." The Trump-Putin summit will include one-on-one talks between the presidents and conclude with a joint news conference, Ushakov said. He said Trump and Putin are expected to issue a joint statement. Ushakov said the Kremlin was satisfied with the talks with Bolton, describing them as "constructive and businesslike." The discussions touched on the state of bilateral ties, nuclear arms control, the situation in Syria, the Ukrainian crisis, developments around North Korea and the US exit from the Iranian nuclear deal — topics Ushakov said would shape the summit agenda.
