The representatives from France, Germany, Holland, Portugal, Spain and Sweden were joined by leading figures from the European Tour, Ryder and PGA, who were also there to listen to presentations outlining the bid process.
They were told that, first and foremost, the development of a world-class golf facility capable of hosting golf's greatest team tournament would be critical, as would ensuring government and private sector support.
The deadline for the submission of bids was set for April 30, 2010, with the host nation for the 42nd edition of the biennial transatlantic contest being announced next year.
All delegates made clear their commitment to hosting the tournament and were optimistic about the golf development opportunities staging such a prestigious event would bring.
European Ryder Cup director Richard Hills said: "It speaks volumes for the global interest in The Ryder Cup that we have six nations eager to host The 2018 match.
"We described the symposium to the delegates as 'Operation Level Playing Field'. We have been transparent in issuing the six nations the important guidelines associated with the evaluation and validation of the bid."
