The United States announced active cooperation with Russia and Ukraine to resolve the conflict.

The United States is actively cooperating with Russia and Ukraine on conflict resolution issues. This was announced on April 1 by White House Press Secretary Caroline Leavitt.

"Our team continues to interact with Russians and Ukrainians, and the President [of the United States Donald Trump] is very actively engaged in this topic every day," the spokeswoman said at a briefing.

Levitt also stressed that Trump is personally very involved in the issue of conflict resolution and wants it to end.

For the parties' reasons: the Russian Federation and the United States have made progress in the "Black Sea Initiative"

It became known what Moscow and Washington agreed on during 12-hour consultations in Riyadh.

Earlier in the day, Kremlin spokesman Dmitry Peskov said that Moscow continues contacts with Washington, despite statements by US President Donald Trump about possible secondary duties on Russian oil.

Earlier, on March 30, Trump announced that he would impose secondary duties on Russian oil exports in the absence of an agreement with the Russian Federation to end the conflict in Ukraine. However, he later added that he would not like to introduce these measures against Russia.
