The Kremlin said on Thursday that the U.S. and Russia have a long way to go before the two countries reach any breakthrough in relations.

“Let’s not talk about any breakthroughs; firstly we should talk about, as a starting point, getting a dialogue going. We have a long way to go before any breakthrough,” Kremlin spokesman Dmitry Peskov told reporters on a press call, according to Reuters.

The Washington Post also reported that a portion of Trump's briefing materials for his phone call with Putin contained the phrase “DO NOT CONGRATULATE” in all capital letters.

Trump took to Twitter on Wednesday to defend the call, saying Russia could help the U.S. in a variety of areas.
