US president reportedly made the invite during a phone call with his Russian counterpart as relations between the two countries grow increasingly frosty، telling him he would be happy to see him at the White House; Trump reportedly said he would also be happy to visit Moscow. US President Donald Trump invited his Russian counterpart Vladimir Putin to the United States during a phone call، and said he would be glad to see Putin in the White House، RIA Novosti reported on Friday، citing the Russian Foreign Ministry. The news agency quoted Foreign Minister Sergei Lavrov as saying Trump returned to the subject of an invitation a couple of times during a phone call with Putin. Trump told Putin he would be happy to make a reciprocal visit to Russia، the RIA news agency quoted Lavrov as saying. "We proceed from the fact that the US president in a telephone conversation...made such an invitation، said he would be glad to see (Putin) in the White House، would then be glad to meet on a reciprocal visit،" said Lavrov، according to a transcript of an interview with RIA on the foreign ministry website. "He returned to this topic a couple of times، so we let our American colleagues know that we do not want to impose، but we also do not want to be impolite، and that considering that President Trump made this proposal، we proceed from the position that he will make it concrete." Rolling out a welcome for Putin in the White House could anger Trump's domestic critics، who accuse Russia of hostile acts against Western countries، including the United States. "I would simply turn your attention to the fact that Donald Trump after this phone conversation has said several times in both Tweets and in words that it is necessary to resolve issues with Russia، we want to have good relations with Russia، this is better than not having good relations، and that only a fool thinks otherwise،" Lavrov said. "We also hear this." Also on Friday، the RIA agency reported that Lavrov said that US military strikes on Syria last week removed any moral obligation Russia had to withhold S-300 anti-aircraft missile systems from its ally Syrian President Bashar al-Assad. Lavrov was also quoted as saying that، prior to the US strikes on Syrian targets، Russia had told US officials which areas of Syria represented "red lines" for Moscow، and the US military action did not cross those lines.
