"Lavrov confirmed that Russia will continue to support the sustainability of the JCPOA", the Russian Foreign Ministry said in a Facebook statement.
Russian Federation is now subject to strict USA sanctions over its 2014 annexation of Crimea.
The Russian foreign minister's comments follow the most recent escalatory back and forth between the US and North Korea.
He said that both Russian Federation and the United States have to address the situation as it is, which he said was created by "the spiral of unfriendly steps started by the Obama administration", but still work like "responsible people" to address their bilateral ties as well as serious global issues.
Earlier that day, before a three-way meeting of the U.S., South Korea and Japan, Trump announced a new executive order applying additional sanctions against those trading with the North. Trump also applauded China's central bank for what he said was an order that other banks "immediately stop doing business with North Korea".

At a news conference Friday on the sidelines of the United Nations General Assembly, Russian Foreign Minister Sergey Lavrov once again hit back on claims his country meddled in the 2016 USA election, saying his American counterpart failed to offer any proof of interference.
Lavrov said Russian Federation would welcome any efforts at mediation, saying "the mediators could be one of the neutral European countries".
The foreign minister spoke to the UN General Assembly two days after US President Donald Trump threatened to "totally destroy" North Korea if it launches attacks on his country or its allies. He added that U.N. Secretary-General Antonio Guterres has talked about mediation and said if he received such a request "he would try to fulfill that".
China's minister for foreign affairs, Wang Yi, was a little more diplomatic. It would halt North Korean nuclear and missile tests in exchange for the US and South Korea stopping their joint military exercises, but the Trump administration has rejected it.
On Friday, Russia urged "hot heads" to calm down as the United States admitted it felt "challenged" by North Korea's warning that it could test a hydrogen bomb over the Pacific.
Lavrov was asked whether he saw a link between the crisis in North Korea and Trump's threat to pull out of the 2015 agreement to cap Iran's nuclear program. "That was mentioned by all the European countries that participated in the negotiations", he said.
