Bin Salman's remarks, which he made on the second day of a high-profile investment conference now underway in Riyadh, came one day after Erdogan revealed details of Khashoggi's October 2 murder in the Saudi Consulate in Istanbul.
Turkish President Tayyip Erdogan spoke to Prince Mohammed on Wednesday and the two discussed the steps needed to bring to light all aspects of the killing of Khashoggi, a presidential source said.
Karen Attiah, Khashoggi's editor at the Washington Post, has said that Saudi authorities imposed a travel ban to put pressure on the journalist's writing.
Most outspoken has been Germany's Angela Merkel, who has halted Germany's arms exports to Saudi while the killing is being investigated, calling Khashoggi's death a "monstrosity". Trump also said the United States has sent officials to Saudi Arabia to get more information on the killing, which has spiraled into a crisis.
Striking a defiant tone, Prince Mohammed told worldwide investors at a major conference in Riyadh that the furor over Khashoggi's killing at the Saudi consulate in Istanbul would not derail the kingdom's reform drive.
Reports said intelligence officers intercepted seven phone calls from a hit squad member to Mohammed bin Salman's private office on the day Mr Khashoggi went missing.

"PM-designate Hariri will stay in Saudi Arabia for two days, so I hope there won't be rumors that he's kidnapped", MBS quipped in remarks to an investment conference in Riyadh, flanked by Hariri and Bahrain's crown prince.
Turkish media have also published a security camera image allegedly showing a vehicle belonging to the Saudi Consulate "scouting" a forest in the outskirts of Istanbul before Khashoggi was killed.
"Those responsible will be held accountable".
"Many are trying to exploit the Khashoggi affair to drive a wedge between Saudi Arabia and Turkey", he said.
Saudi officials have denied permission to Turkish police to search a well in the garden of their consulate in Istanbul, as probe intensified to find the body of Jamal Khashoggi, the Anadolu news agency reported today.
Investigators emptied the well and are awaiting the results of an analysis of the water to determine whether body parts were dumped there, according to Yeni Safak, a pro-government Turkish newspaper.
