US diplomats have on several occasions intervened to convince foreign governments to buy aircraft from boeing rather than its European rival airbus, newly released diplomatic cables show.
The cables, obtained by the New York Times from the whistle-blower website WikiLeaks, document several incidents in which diplomats were involved in haggling over the billion-dollar deals seen as key to US economic growth.
One cable describes Saudi King Abdullah responding favourably to a personal request from then-President George W. Bush in 2006 that he buy as many as 43 Boeing jets for Saudi Arabian Airlines and another 13 for the royal fleet.
But the king "wanted to have all the technology that his friend, President Bush, had on Air Force One," the cable said.
Once the king's own plane was outfitted with the world's most advanced telecommunications and defence equipment, "'God willing,' he will make a decision that will 'please you very much,'" the cable said.
In November, state-owned Saudi Arabian Airlines said it had signed a contract for 12 new boeing 777-300ER jets worth some $3.3 billion.
The State Department confirmed to the Times that it had authorised an "upgrade" to the king's plane but declined to provide further details on security grounds.
In another incident, Bangladesh's Prime Minister Sheikh Hasina demanded landing rights for its national carrier at New York's John F Kennedy International Airport as a condition for a boeing deal.
"If there is no New York route, what is the point of buying boeing," she was quoted as saying in a November 2009 cable.
The deal went through, but so far Biman Bangladesh Airlines has not been given the landing rights, the Times said.
The Times said such practices have continued despite decades-old agreements between US and European leaders to keep politics out of airline deals.
But State Department officials interviewed by the newspaper defended their involvement, saying such high-value exports were crucial to US President Barack Obama's efforts to pull the country out of its economic slump.
"That is the reality of the 21st century; governments are playing a greater role in supporting their companies, and we need to do the same thing," Robert Hormats, under secretary of state for economic affairs, told the Times.
