Naranjo has been campaigning for Costa Rica to take over the rotating seat on the Security Council now held by Honduras when the seat becomes vacant at the end of the year.

Last year, despite personal lobbying by Costa Rican President Jose Maria Figueres, a grouping of lesser-developed nations known as the Non-Aligned Movement rejected Costa Rican membership when Arab nations objected to the presence of the Costa Rican Embassy in Jerusalem.

Naranjo said this week that he had not seen the published report, but said Costa Rica would "absolutely" not move its embassy, chuckling at the suggestion it would.
