A crucial meeting to repair one of the world’s most important diplomatic relationships began with a fist bump Friday as Saudi Crown Prince Mohammed bin Salman welcomed U.S. President Joe Biden at a royal palace.

The first encounter, captured by Saudi television, occurred as Biden stepped out of his presidential limousine in Jeddah for a visit that is intended to reset their countries’ longstanding partnership.

There was little evidence of any warmth between the leaders, and none of the backslapping or smiles that Biden or the crown prince usually display when greeting other leaders.

Until now, Biden had refused to speak to Prince Mohammed, the presumed heir to the throne currently held by his father, King Salman. Biden has harshly criticized the oil-rich kingdom for its human rights abuses, particularly the murder of Jamal Khashoggi, a U.S.-based journalist.
