The possible measures for the European Union to undertake listed in the note include seeking "a public or written reassurance" from US President Donald Trump that the new sanctions, if imposed, will not be targeting EU interests, the media said.
Other option proposed in the note is to use European law to prevent the new sanctions from being "recognized or enforceable" in the European Union, as well as to prepare "WTO-compliant retaliatory measures."
On Saturday, the US congress released the text of the bill targeting Russia, Iran and North Korea, which both chambers of the Congress agreed upon. The voting in the House of Representatives will reportedly take place on Tuesday.
The proposed bill views Russia's Nord Stream 2 gas pipeline project as a threat to energy security of Ukraine and the European Union, proposing to provide US allies with financial aid to counter alleged Russian influence and possible cyberattacks by Russian hackers.
On Saturday, media reported citing a statement by a representative of the European Commission that Brussels warned Washington about unilaterally tightening sanctions against Russia.
Kremlin spokesman Dmitry Peskov told Sputnik on Saturday, that Moscow viewed the bill negatively.
