Russia has made it clear the country will be sticking with the Paris climate change agreement.
This follows Donald Trump's announcement the United States will be withdrawing from the planned accord to reduce global greenhouse gas emissions.
In a press conference on Thursday, the US president said the agreement would represent a "punishment" to America.
Russia reaffirmed its commitment to the accord in a statement by Deputy Prime Minister Arkady Dvorkovitch, who made it clear the decision to sign the Paris agreement would not be reversed.
The US is the third country in the world after Syria and Nicaragua to refuse to take part in the agreement, which was signed in 2015 and came into effect in November 2016.
