Russian President Vladimir Putin and Saudi Arabia's Crown Prince Mohammed bin Salman bin Abdulaziz Al Saud shared a hearty handshake at the G20 summit in Argentina because they have good personal relations, Kremlin Spokesman Dmitry Peskov told reporters, TASS reports.
'Our relationship with Saudi Arabia is important to this country, but that does not prevent us from putting forward robust views on these matters of grave concern'.
Saudi Arabia has led a boycott of the tiny Gulf state since past year.
Algerian Prime Minister Ahmed Ouyahia greeted the prince on the tarmac late Sunday and held talks with him on Monday in Bouteflika's absence.
Abdulaziz plans to argue that his co-operation with Khashoggi was "a crucial factor" in the decision to have the USA -based columnist for The Washington Post killed and that there was a direct link between the surveillance carried out on Abdulaziz and the slaying.
The Argentine president let it be understood that he discussed the Khashoggi killing with Turkish President Recep Tayyip Erdogan, a persistent crown prince Mohammed critic, but not with the prince himself.
Throughout the exchange, the Crown Prince assures Mr Macron that he can handle the situation and he "can deal with it".
Mrs May told MPs: 'I met Crown Prince Mohammed bin Salman, first to stress the importance of a full, transparent and credible investigation into the bad murder of Jamal Khashoggi, and for those responsible to be held to account - a matter which I also discussed with President Erdogan.
Saudi authorities have vehemently denied the crown prince was involved. The G20 summit is the Crown Prince's first major gathering of worldwide political leaders since the murder, and his attending the summit in itself was a calculated risk.
"And when it is done, when you complete that analysis, there's no direct evidence linking him to the murder of Jamal Khashoggi".
'Leaders should not just offer warm words against human rights atrocities, but back their words up with action.
