Putin continued, "I hope that after you assume the position of the President of the United States of America, we will be able -- by acting in a constructive and pragmatic manner -- to take real steps to restore the framework of bilateral cooperation in different areas as well as bring our level of collaboration on the international scene to a qualitatively new level."
The release of the letter -- which was confirmed as authentic by Moscow -- comes days after Russia loudly voiced complaints about its relationship with the US under the Obama administration, and after ambiguous remarks from Trump about the need to "strengthen and expand" US nuclear capability to counter nuclear adversaries.
At his annual year-end news conference on Thursday
, Putin said that the US and Russia "need to discuss ways to normalize our relations. During his election campaign, Trump said it would be proper to normalize and it can't be worse, and I agree with him."
A Kremlin spokesperson criticized the poor relationship with the Obama administration in an interview Wednesday.
"Nearly all levels of our dialogue (with the US) has been frozen," Kremlin spokesman Dmitry Peskov told Russian state-run news agency RIA Novosti
. US State Department spokesperson John Kirby pushed back on Peskov's assessment, saying Thursday that "diplomatic engagement with Russia continues across a wide range of issues."
Still, the sharp rhetoric from each side stems from serious disagreements over crises in Syria and Ukraine, and allegations by the US against Russia of covertly interfering in the 2016 election by hacking -- to the advantage of Trump, according to the intelligence community.
Adding to the tension is Trump's cavalier dismissal of nuclear proliferation concerns -- he reportedly told MSNBC on Friday, "let it be an arms race." And incoming new White House press secretary Sean Spicer added to Trump's comments by saying on CNN, "If another country or countries want to threaten our safety, our sovereignty, [Trump's] going to do what it takes."
