On July 6 , 2017 , during a speech in Warsaw , Poland , Trump urged Russia to cease its support for " hostile regimes " in Syria and Iran . On July 7 , 2017 , in what appeared to be a sign of good relations between the leaders of both countries , Trump met with Putin at the G20 Hamburg summit in Germany and described the meeting as " an honour . " In mid-July 2017 , the Russian foreign ministry noted that the staff of the U.S. Embassy in Moscow , following expulsion of diplomats by the Obama administration in December 2016 , far exceeded the number of Russian embassy employees in Washington and indicated that the Russian government was considering retaliatory expulsion of more than thirty-five U.S. diplomats , thus evening out the number of the countries ' diplomats posted . On July 28 , Russia announced punitive measures that were cast as Russia 's response to the additional , codified , sanctions against Moscow passed by Congress days prior , but also referenced the specific measures imposed against the Russian diplomatic mission in the U.S. by the Obama administration . Russia demanded that the U.S. reduce its diplomatic and technical personnel in the Moscow embassy and its consulates in St Petersburg , Ekaterinburg and Vladivostok to four hundred fifty-five persons — the same as the number of Russian diplomats posted in the U.S. — by September 1 ; Russia ’s government would also suspend the use of a retreat compound and a storage facility in Moscow used by the U.S. by August 1 . Two days later , Vladimir Putin said that the decision on the curtailment of the U.S. diplomatic mission personnel had been taken by him personally and that 755 staff must terminate their work in Russia . After the sanction bill was on August 2 signed by Donald Trump , Russian prime minister Dmitry Medvedev wrote that the law had ended hope for improving U.S. – Russia relations and meant " an all-out trade war with Russia . " The law was also criticised by Donald Trump , whose signing statement indicated that he might choose not to enforce certain provisions of the legislation that he deemed unconstitutional
