UNITED NATIONS — Panama won a seat on the U.N. Security Council with the 48th ballot yesterday after American-backed Guatemala and Venezuela, led by leftist President Chavez of Venezuela, dropped out to end a deadlock.

Panama got 164 votes in the 192-member U.N. General Assembly, more than the 120 needed to win a two-year term starting January 1 on the U.N.’s most powerful body. Venezuela got 11 votes, Guatemala 4 votes, and Barbados 1 vote.

The race for the council seat, which began October 16, became highly political because of America’s support for Guatemala and Mr. Chavez’s speech at the General Assembly in September in which he called President Bush “the devil.” A number of countries said Mr. Chavez’s anti-Bush comments hurt Venezuela’s chances.

Guatemala led Venezuela in all but one of the 47 ballots but couldn’t muster the two-thirds support needed to win in the General Assembly. The standoff was the third-longest battle for a seat on the Security Council in the U.N.’s 61-year history.

The General Assembly president, Sheikha Haya Rashed Al Khalifa, who announced the results, said she was “delighted”that all five new members of the Security Council had now been chosen — Belgium, Indonesia, Italy, Panama, and South Africa.

Diplomats in the assembly chamber burst into applause when Panama’s election was announced.

Panama’s election was virtually assured last week when the foreign ministers of Guatemala and Venezuela met and agreed to withdraw in favor of the Central American nation, which they called a bridge between the northern and southern nations in Latin America. The 34 Latin American and Caribbean nations endorsed Panama as the group’s candidate on Friday.

Panama’s U.N. Ambassador Ricardo Alberto Arias has said his country presented its name in “a spirit of understanding the different conflicts that there are in the world, especially those caused by cultural and religious differences.”

Because of Panama’s very diverse culture and its different races and religion, he said the country can “contribute to peace and international stability.”

Mr. Arias stressed that together with Peru, whose term on the council goes through 2007, Panama will defend the interests of Latin American and Caribbean countries.

The Security Council has five permanent members — Britain, China, France, Russia, and America. The other 10 seats, filled for two-year terms, are portioned out to the five U.N. regional groups.

The second highest number of ballots was 52, set in 1960.
