BEIRUT, Lebanon — It seems that everyone wants something from Saudi Arabia.

Before becoming the president of Egypt, Mohamed Morsi wanted visas to take his family on a religious pilgrimage. A Lebanese politician begged for cash to pay his bodyguards. Even the state news agency of Guinea, in West Africa, asked for $2,000 “to solve many of the problems the agency is facing.”

They all had good reason to ask, as the kingdom has long wielded its oil wealth and religious influence to try to shape regional events and support figures sympathetic to its worldview.

These and other revelations appear in a trove of documents said to have come from inside the Saudi Ministry of Foreign Affairs and released on Friday by the group WikiLeaks.

While the documents appear to contain no shocking revelations about Saudi Arabia, say, eavesdropping on the United States or shipping bags of cash to militant groups, they contain enough detail to shed light on the diplomacy of a deeply private country and to embarrass Saudi officials and those who lobby them for financial aid. And they allow the curious to get a glimpse of the often complex interactions between a kingdom seen by many as the rich uncle of Middle East and its clients, from Africa to Australia.
