"We reserve the right to make a decision on how many American diplomats there are in Moscow. But we will not do that for the moment," Putin told a press conference after a summit of BRICS nations in southern China.
Moscow had previously ordered the US to reduce its diplomatic presence to 455 people by September 1, the same number that Russia has in the US.
That number, however, includes 155 people who work for Russia's diplomatic mission to the UN in New York, Putin said, meaning his country could further cut the number of US diplomats to 300: "It's 455 minus 155."
Russia demanded Sunday that the US rethink its shuttering of Moscow's diplomatic premises, insisting that Washington bore sole responsibility for worsening ties after the "hostile act".
