Iran announced on Sunday a further rollback of its commitments to its nuclear accord, while Iraq's parliament demanded the departure of American troops from the country as fallout from the attack spread.
About 5,000 US troops remain in Iraq.
The Iraqi resolution specifically calls for ending an agreement in which Washington sent troops to Iraq more than four years ago to help in the fight against the Islamic State group.
There have been emotional rallies attended by thousands of people in both Baghdad and Tehran calling for retaliation on the USA for Soleimani's assassination.
Soleimani, who spearheaded Iran's Middle East operations as commander of the Revolutionary Guards' Quds Force, was killed in a United States drone strike Friday near Baghdad airport.
They also discussed the future of relations between Iraq and the worldwide coalition against Daesh/ISIS and the war on terrorism.
Soleimani was killed last week in Baghdad after President Trump authorized an airstrike against him. "We must attack all that are in the range of our missiles", said the 61-year-old businessman who gave his name as Afkhami.

Kejriwal had called a meeting at his residence over Sunday's violence. "We condemn this violence by ABVP and its supporters". Banerjee [on JNU violence] make us suspicious that on whose side she is, those who are against the country", he asked.
The Iraqi Parliament's resolution follows the death of Soleimani on January 3, who was killed in a USA airstrike in Baghdad's worldwide green zone.
Former Vice President Joe Biden said Trump was ill-prepared for the repercussions of the strike on Soleimani and had alienated allies by not alerting them of the plans.
Markets were braced for further turmoil on Monday as the war of words between Iran and the United States turned increasingly hostile, threatening to destabilise the world's most important oil producing region.
Pompeo said only that any USA military strikes inside Iran would be legal.
In a statement, the government said Abdul-Mahdi spoke with French Foreign Minister Jean-Yves Le Drian by phone, informing him of the move.
Trump claimed Soleimani was responsible for the deaths of thousands of Americans, Iraqis and Iranians, saying the longtime Iranian general "made the death of innocent people his sick passion" while helping to run a terror network that reached across the Middle East to Europe and the Americas.
Trump also vowed to impose sanctions on Iraq if a move to evict United States military personnel from the country takes place, a possibility heightened by the Iraqi Parliament's passage Sunday of a measure to expel foreign troops. "He had carried a lot of political weight and influence among the Iranian regime's regional proxies and political allies", he said.
Soleimani was often seen holding talks with politicians in Baghdad to promote the formation of an Iraqi cabinet that would have Iran's approval.
