Prince Turki bin Faisal made the remarks during an address to the 27th annual Arab-US Policymakers Conference in Washington on Wednesday.

He denounced attacks on Saudi Arabia in the wake of Khashoggi’s murder inside the kingdom’s Istanbul consulate on October 2.

“The tragic and unjustified” slaying of Khashoggi “is the theme of today’s onslaught and demonization of Saudi Arabia in the same fashion as the previous crises. The intensity and gleefulness of it is equally unfair,” he said. “Subjecting our relationship to this issue is not healthy at all.”

Turki also noted that Saudi Arabia’s “strategic relationship” with the US had survived crises for more than 70 years.

“Nowadays, this relationship is once again threatened,” he said, adding, however, that the bilateral ties are “too big to fail.”

The Saudi prince further claimed that the kingdom is committed to bringing to justice those responsible for Khashoggi’s death “and whoever else failed to uphold the law.”

Khashoggi, an outspoken critic of Saudi Crown prince Mohammed bin Salman, entered the consulate in Istanbul to get the papers needed for his marriage, but never left the building.

After weeks of denials of any involvement in Khashoggi’s disappearance, Saudi Arabia eventually acknowledged that he had been killed in a “premeditated” operation.

Turkey’s chief prosecutor said Khashoggi had been strangled upon his arrival at the Saudi mission and then dismembered.

Faisal’s comments come as US Congress has stepped up pressure on President Donald Trump to punish the Riyadh regime for the murder, which is widely believed to have been ordered by Crown Prince Mohammed bin Salman.

Several US lawmakers have called for sanctions against the kingdom, while others want Washington to stop its nuclear talks with Saudi Arabia.

However, Trump – who stands accused inside the US and abroad of seeking to cover up the crime – appears to be reluctant to pose any risk to billions of dollars worth of arms deals and investments in the kingdom.

The Trump administration has courted the Saudis as they seek to build tens of billions of dollars worth of nuclear power facilities. The US has also been the major provider of weapons to the Saudi regime amid its bloody war on Yemen.

Trump says doesn’t feel ‘betrayed’ by Saudis

In fresh comments on Wednesday, US President Donald Trump said he does not feel “betrayed” by the Saudis over Khashoggi’s death but “maybe they’ve betrayed themselves.”

“Not betrayed me, no. I just hope that it all works out. We have a lot of facts, we have a lot of things we have been looking at, they have not betrayed me no, we just have to see how it all turns out,” he told reporters at the White House.
