Jewish Agency Chairman Sallai Meridor departed yesterday for a ten-day visit to the Jewish communities in Chile, Argentina and Uruguay. He will meet in Chile with the heads of the 21,000- member Jewish community to examine Jewish Agency operations in that country. He will then head for Uruguay, where he will discuss ways in which to help the economically-distressed Jewish community of 22,500. Uruguay's Jews, concentrated mostly in Montevideo, the capital, are undergoing a crisis similar to that of Argentina, and the Jewish Agency has recently requested that the Government of Israel give the same assistance to immigrants from Uruguay as it does to Argentine olim (immigrants). Meridor's last stop will be in Argentina, from where 3,125 immigrants have arrived this year. Only 1,413 arrived during all of 2001.
