Costa Rica congress approves telecoms opening

(Adds quote from interview with Slim)

SAN JOSE, Costa Rica, May 15 (Reuters) - Costa Rica's Congress has approved the opening of the Central American country's telecommunications sector to private investment in cellular phones and Internet services.

"The telecommunications bill passed by a vote of 35 to 14" Wednesday, congressional spokeswoman Ana Isabel Duran said on Thursday.

The vote ended a long battle over the measure, which allows private companies to buy concessions from the state-owned telephone company to operate cell phone and Internet lines and was part of the Central American Free Trade Agreement (CAFTA).

Fixed telephone lines will remain in the hands of the state-owned Costa Rican Electricity Institute.

Costa Ricans approved CAFTA in a referendum last Oct. 7, lagging behind other countries in the region. Implementation of terms of the deal was left to the Congress.

Mexico's America Movil (AMXL.MX: Quote, Profile, Research, Stock Buzz), owned by billionaire Carlos Slim, and Spain's Telefonica (TEF.MC: Quote, Profile, Research, Stock Buzz) are the major players in the Latin American cellular phone market.

Slim, one of the world's richest men, said he was interested in looking at the newly opened market.

"We'll have to see what the auction conditions are like," Slim told Reuters.
