Saudi Arabia’s finance minister Mohammed al-Jadaan met US Treasury Secretary Steven Mnuchin in Riyadh, a statement from the ministry said on Tuesday.
Mr Mnuchin said on Sunday that Saudi Arabia’s explanation of the killing of journalist Jamal Khashoggi was a “good first step but not enough”, adding that it was premature to discuss sanctions over the incident.
Mr Mnuchin is touring the region to discuss counter-terrorism measures with Arab allies.
Meanwhile, Saudi Arabia’s foreign minister said the investigation into the killing of Mr Khashoggi will produce the truth about what happened.
Adel al-Jubeir also pledged that mechanisms will be put in place so that “something like this can never happen again”.
He spoke on Tuesday in Indonesia, just hours before Turkey’s president Recep Tayyip Edrogan is expected to detail his own country’s findings into the matter.
Mr al-Jubeir said Saudi Arabia is committed to ensuring “that the investigation is thorough and complete and that the truth is revealed and that those responsible will be held to account”.
Saudi Arabia has acknowledged that Mr Kashoggi died on October 2nd during a visit to the kingdom’s consulate in Istanbul.
The country maintains he died in a “fistfight”. Turkish officials said the 59-year-old was attacked and killed by a 15-man Saudi team.
Mr Erdogan has said he will “go into detail” about a case that has shocked the world and raised suspicions that a Saudi hit squad planned Mr Khashoggi’s killing after he walked into the consulate, then attempted to cover it up.
The Turkish president promised the case “will be revealed in all its nakedness” in a speech to ruling party members.
Stream of leaks
A stream of leaks to national and international media has increased pressure on Saudi Arabia, which is hosting a major investment conference this week which many dignitaries have decided to skip because of the scandal.
Saudi Arabia said 18 Saudis were arrested and that several top intelligence officials were sacked over the killing, but critics have alleged that the punishment was designed to absolve Crown Prince Mohammed bin Salman, the kingdom’s heir-apparent, of any responsibility.
On Monday, leaked surveillance video showed a man strolling out of the diplomatic post hours after Mr Khashoggi disappeared into the consulate, apparently wearing the Washington Post columnist’s clothes as part of a macabre deception to sow confusion over his fate.
Mr Khashoggi had gone to the embassy to pick up some papers he needed in order to get married.
US president Donald Trump said he is not satisfied with the explanations he has heard about Mr Khashoggi’s death.
Mr Trump said: “We’re going to get to the bottom of it. We have people over in
Saudi Arabia now. We have top intelligence people in Turkey. They’re coming back either tonight or tomorrow.
“We’re going to know a lot over the next two days about the Saudi situation,” he said. “It’s a very sad thing.”
Mr Trump spoke on Sunday with Crown Prince Mohammed. “He says he is not involved nor is the king,” Mr Trump told USA Today.
The newspaper said Mr Trump declined to say whether he believed the prince’s denials.
If their involvement was proven, Mr Trump said: “I would be very upset about it. We’ll have to see.”
