The first delegations participating in the South American Energy Summit arrived Sunday in the Island of Margarita, eastern Venezuela.

The delegations of Argentine and Uruguay -headed by Vice-President Rodolfo Nin Novoa- arrived in Hilton Hotel on Sunday amid stringent security measures. The Presidential Guard and other state security corps prevented free passage even to reporters for coverage of the event.

The press office for the summit was installed in a tent outside the hotel, provided only with basic phone and internet services with restricted use.

Sources said only cameramen and photographs would be allowed in the plenary session, and a special press room would be available for interviews.
