Jewish Agency Chairman Sallai Meridor departed yesterday for a ten-day visit to the Jewish communities in Chile, Argentina and Uruguay. He will meet with the heads of the 21,000- member Chilean-Jewish community to examine Jewish Agency operations there. He will then head for Uruguay, where he will discuss ways in which to help its economically distressed Jewish community of 22,500. Uruguay's Jews, concentrated mostly in Montevideo, are undergoing a financial crisis similar to that of Argentina, and the Jewish Agency recently requested that 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.
