She was speaking after the White House said on Sunday that U.S. President Donald Trump was open to signing new legislation after Senate and House leaders reached agreement on a sanctions bill late last week.
"The attitude to this (law) will be formed on the basis of a thorough analysis, and the decision (on how to respond) will certainly be taken by the head of state, President Putin", Dmitry Peskov, Putin's spokesman, told a conference call with reporters.
Russian officials welcomed Donald Trump's presidential win past year, hoping to mend relations with the United States which reached a post-Cold War low under President Barack Obama. However, the congressmen did not include a provision which would facilitate the process of lifting sanctions from Russian Federation. But six months into Trump's presidency ties between the two countries remain tense, and the much-anticipated first meeting between Trump and Russian President Vladimir Putin early this month did not seem to produce any tangible results.
"Russian-U.S. cooperation in resolving major global problems, including countering worldwide terrorism, will be extremely hard, if at all possible", Sputnik quoted Klintsevich as saying.
Russian Deputy Foreign Minister Sergey Ryabkov on Wednesday slammed the USA move to impose fresh sanctions on Moscow, calling it "destruction of prospects for normalising relations between the two countries".
U.S. -Russia relations were entering "uncharted territory in a political and diplomatic sense", he added.
