Iranian Foreign Minister Abbas Aragchi arrived in Russia, following talks with other nations over the weekend, BBC reports.
He is set to meet Russian President Vladimir Putin in Moscow later today, the BBC's US partner CBS News reports.
Araghchi's visit comes after a trip to Oman, where he says talks focused on "ways to ensure safe transit that is to benefit of all dear neighbors and the world" in the Strait of Hormuz.
Over the weekend, the foreign minister also said he had a “very fruitful” visit to Islamabad, where he “shared Iran's position concerning workable framework to permanently end the war on Iran”.
“Have yet to see if the U.S. is truly serious about diplomacy,” he wrote on social media on Saturday.
Aragchi’s comments were followed by news that Donald Trump had cancelled plans for US envoys Steve Witkoff and Jared Kushner to visit Islamabad for peace discussions with Iran.
Both sides remain locked in a standoff over the Strait of Hormuz despite Trump's extension of a ceasefire that had been due to expire on 22 April to allow talks to continue.
