Japan, the European Union, Norway and the United States will call for an increase to the $4.5 billion in aid already pledged for war-torn Sri Lanka at their review meeting Tuesday in Tokyo, according to sources close to the matter.

Representatives from 51 countries and 22 international organizations got together in June 2003 in Tokyo to pledge the four years' worth of aid to help rebuild Sri Lanka. The four served as cochairs of the donors' meeting and have carried out periodic review meetings.

At the upcoming evaluation meeting, the eighth of its kind, attendants from the four cochairs will exchange information about the recently intensifying conflicts between the Sri Lankan government and the separatist rebel Liberation Tigers of Tamil Eelam.

They will also review reconstruction activities over the past three years and issue a joint statement to call for an increase in the pledged aid amount, the sources said.
